1. Welcome to the Passion People!
On the fully hydraulic MAGURA disc brake system Marta, Marta SL and Marta SL
Magnesium the braking force is transmitted to the braking surface by a mineral oil column.
The movement of the lever blade moves a piston, which is integrated in the brake lever
(master cylinder). The piston pushes the mineral oil column through the brake hose in the
direction of the brake caliper, where two pistons, on which the brake pads are fixed, are
pushed out. The friction between the brake pads and the rotor slowes down the bicycle and
causes both the rotor and the brake caliper to heat up.
Never touch either the rotor or the brake caliper after long braking as this may
cause serious burns
You will be pleased to find out that the MAGURA Marta disc brake offers a superior
braking power even with little hand force applied, no matter what the weather conditions
should be. Particularly in wet weather conditions disc brakes are much more responsive
than rim brakes and transmit their enormous power immediately after activating the brake
lever.
Disc brakes don’t wear your rims down. However if they have been mounted incorrectly
they might cause a squealing noise during braking, mainly during wet weather conditions.
This manual contains important information about the safe installation,
operation and maintenance of your MAGURA disc brake. We urge you to read
it carefully, become familiar with its contents and follow our recommendations to
help make your new braking experience enjoyable and trouble free.
All steps will be explained on the Marta model. The Marta SL and Marta
SL Magnesium are technically identical, with the exception of the carbon lever blades
(which are compatible with Marta).
Although the Marta disc brake system is relatively simple you should not ove-
restimate your technical skills! We therefore advise you to leave the following opera-
tions to a trained technician of a professional bike shop.
Should there be any further questions or problems we warmly recommend that
you visit our website www.magura.com where you will always find the newest and
hottest tips about all our products. On magura.com you can also dowload this manual in
a convenient A4 format and get online help around the clock for free. Stay tuned with the
Passion People!
Thank you for your confidence in our products, enjoy your ride and your new
MAGURA disc stoppers!
Happy trails!

Congratulations! You have purchased a
fully hydraulic MAGURA disc brake proudly
„Made in Germany“. You will be amazed
at he awesome braking power and the
minimum amount of maintenance that is
necessary on our stoppers. Good to know
that you are not alone, millions of riders
worldwide rely on them and every day our
numbers are increasing.

1. Always make sure that the quick release skewers of your wheels and seat post are
correctly mounted and closed.
incorrectly installed quick release skewers might cause the fixed items to
become loose. Serious accidents with severe injury may result!!
2. Always make sure that the brake lever pressure is o.k. by pulling the lever blade and
ensuring that full braking performance is achieved before the lever blade touches the hand-
lebars. If this is not the case, pull the lever blade several times (pump) until the brake pads
touch the rotor.
Changing pressure points during a ride might be the result of having air in the brake
system.
See hints about filling and bleeding from on pages 15/16.

always check carefully the following points:
1. Are you already familiar with hydraulic disc brakes? Our brakes might be much more
powerful than the stoppers on which you relied so far.
Take your bicycle to a safe area to learn the proper braking technique and operation of your
new brakes and your bike.
2. Check whether you activate the front brake with the brake lever, which you
are used to braking on the front. If ever this is not the case you will have to train
your new setup because any unintended braking might cause an accident with pos-
sible heavy bodily injury! Change the hose connection by a trained technician in case
of any doubts.
For further hints concerning swapping of the brake hose see page 10 onwards.
3. New brakes and new rotors or brake pads must always be run in by
braking at least 30 times from a speed of 30 km/h to achieve the maximum brake
power. Take your bike to a safe place to run in the brake.
4. While riding in extreme riding conditions (total weight of bike plus rider
over 100 kg and/ or a gradient of more than 15 %) always use both brakes simulta-
neously to slow your bike down.
5. Use the brakes according to the user chart on page 2 of this manual. Any
misuse might cause serious accidents with fatal injuries to yourself and others!
6. Are you familiar with the other components on your bike such as gears, clipless
pedals and suspension units? Always practise using your bike in a safe area to improve your
handling abilities before using it on the road. Consult the user’s manual of your bike to learn
more about this.
7. For your own safety always wear a helmet when you ride a bicycle. Make sure
as well that you wear the suitable clothing and footwear.

3. Always make sure that the brake system does not have any leaks by activating the
lever blade, holding it and checking the hose connections and reservoir cover for eventual
leaks. (Also see page 11)
4. Always protect your rotors and brake pads from oil and lubricants (e.g. by lubricating
your chain). Avoid detergents and soap on the brake pads. Contaminating the pads with
oil and lubricants will cause a permanent loss of braking power. Such contaminated
pads can no longer be used nd should be replaced! Clean a contaminated rotor with dis-
hwater or alcohol.
See further hints about changing the brake pads on pages 12- 13.
5. Release your brake lever and check whether your wheel moves freely and without
drag. Check eventually whether the wheels are correctly mounted and if the quick release
skewers are tightened sufficiently. (Also see page 9)
6. Are your tires in a good condition, and have they enough air pressure? Test this
with your fingers. Lift up your bike and turn the wheels of your bike. An insufficient rotation
might be due to damaged tires, broken axles and/ or broken spokes.
7. Pick up your bike and let it drop from a moderate height. Be careful in case of any
rattling noises. If any are heard check the bearings and all screwed connections.
8. Always follow the instructions given in the owner’s manual of your bicycle.
Never use your bicycle if any of the points mentioned above relate to your bicy-
cle! Consult a professional bike mechanic if you feel unsure. A faulty bicycle might
cause serious accidents with possible fatal injuries of the rider!
In case of a disc brake equipped bicycle you should always keep in mind the fol-
lowing points:
Never activate the lever blade without the brake pads in place and the wheels moun-
ted. In case this should have happened see page 10 of this manual.
Never throw away the transport device, which has been delivered with the
brake. Always clip it between the brake pads whenever the wheel is removed (e.g.
transport of the bike).
Always carefully remove the wheels. Make sure that the rotors are not damaged, defor-
med or contaminated with lubricants.
If the bike is transported upside-down squeeze before (with mounted wheel or
transport device!) the lever blade, hold pressure and fix the blade in this position
with a rubber band or a cable tie.
During transport in an aircraft you can leave your brake as it is, e.g. you do not have to
empty it.

completely different and not compatible! Never mix and match parts from the diffe-
rent models! Any misuse might cause serious accidents!
MAGURA manufacture these braking systems according to the valid standards and
make many rigorous product tests. Because of the large variety of forks and frames availa-
ble on the market it is impossible for MAGURA to test all possible combinations. If you
mount any of our brake systems always make sure that the brakes are in conformity with
the bicycle.
Disc brake calipers can generate a lot of heat during extreme riding conditions.
The resulting heat transfer from the caliper to the fork and/ or frame can have a
negative influence on the mechanical characteristics of both the fork and/ or the
frame.
Insufficient heat transfer from the brake caliper to the frame and the fork,
caused by fork and or frame components having low heat transfer characteristics
(e.g. carbon rear triangles) can cause the brake to overheat, with the possibility of a
total failure of the brake system. This can cause serious personal injury to yourself
and/ or others.
With respect to product liability we remind all our users that any manufacturer
(also: bike mechanic or end consumer!) is responsible for the correct
function of the complete bicycle in this context. Improper combinations and insuffici-
ent installation can cause damage and serious accidents!
2. Mount the brake lever to the handlebar with a 5 mm allen key. Tightening torque 4
Nm/ 34 in.lbs
Hint: Tighten the brake lever so that it can still rotate around the handlebar in case
of a crash. This old motocross trick will reduce considerably the risk of a damaged
brake lever.
The MAGURA disc brake Marta is compatible with frames and forks which meet
the International Standard (IS) and for Postmount (PM) mounts. Depending on the
mounting standard and/or rotor size adaptors are used for a proper installation (cf.
table on page 21). Never mount the brakes with adapters or brackets from other
manufacturers! All warranty will be void in case of any misuse! Use only direct moun-
ting parts from MAGURA or the frame or fork’s manufacturer!
Make sure that the caliper fitting eyelets on your frame or fork are free of any paint,
powder coating or burrs. (arrows). If this is not the case you should contact your dealer who
will be able to clean the surfaces providing an absolutely flat/even mounting surface with
the help of the MAGURA Gnann-o-mat disc optimizer tool (also see page 9).
ATTENTION: The treatment of suspension fork lower legs made of magnesium
might be dangerous because of corrosion! Always follow the safety instructions
given by the respective manufacturer! Always make sure after having treated the
disc brake mounts that these are protected against corrosion by using an appropri-
ate protective paint.

3. Mounting on IS mounts:
Mount the adaptor onto the fork or the frame. Use a 5 mm allen key. Please follow carefully
the mounting instructions that come with the respective adaptor! If you use a thru-axle hub
on the front you might have to use thicker 3 mm spacers (depending on fork model). These
are available separately (code: 0720 829).
Tightening torque: 6 Nm/ 51 in.lbs.
4. Caliper installation: Mount the caliper with MOUNTED wheel and rotor onto the
adaptor. For a better understanding the mounted wheel is not shown on this picture. Do not
tighten the caliper bolts yet! Squeeze the lever blade and keep the pressure. Tighten now
the bolts. Tightening torque: 6 Nm/ 51 in.lbs.
5. Mount the rotor with the 6 Torx T25 bolts onto the hub. Watch out for the correct
rotation direction of the rotor (laser arrow). Use only new original bolts or thread lock if you
use old bolts. Tighten the bolts in a crossed pattern! Tightening torque: 4 Nm/ 34
in.lbs.
6. The transport device prevents the brake pads from being pushed out too far by
unintended lever squeeze when the wheel is removed. It is impossible then to install the
wheel with the rotor. So never throw away the transport device but keep it and always clip it
between the brake pads as shown when the wheel is removed.
Install the wheel by positioning the rotor between the brake pads and fixing the wheel in the
dropouts. Close the quick release of your wheel which you should mount on the opposite
side of the brake caliper and tighten it sufficiently.
7. Squeeze the lever blade several times (pump) to push the pads to their proper
position until the lever feel becomes very firm. Tighten now the caliper fitting bolts.
Tightening torque: 6 Nm/ 51 in.lbs.
8. Mounting on PM mounts:
For Postmount 6” installation in combination with a 160mm rotor, Postmount 7” with
180mm rotor or Postmount 8” with a 203mm rotor on the front you do not need an adaptor.
Mount the caliper DIRECTLY onto the fork with MOUNTED wheel and rotor. For a better
understanding the mounted wheel is not shown on this picture. Do not tighten the caliper
bolts yet! Squeeze the lever blade and keep the pressure. Tighten now the bolts. Tightening
torque: 6 Nm/ 51 in.lbs. Further mounting alternatives cf. page 21 of this manual.

Install the wheel by positioning the rotor between the brake pads and fixing the wheel
in the dropouts. Close the quick release of your wheel which you should mount on the
opposite side of the brake caliper and tighten it sufficiently. As to thru-axle hubs or
wheels consult the manual of the respective fork manufacturer.
Squeeze the lever blade several times (pump) to push the pads to their proper position
until the lever feel becomes very firm.
Do not worry when you hear friction between rotor and pads. A slight drag is
normal on disc brakes with automatic pad wear adjustment during the break-in peri-
od. This drag will disappear after a while. The reason for this is that the brake pads
find their optimum working position towards the rotor, only after a slight wear duri-
ng the break-in period. Slight drag might also happen after a brake pad change or in
case of an incorrectly installed wheel.
In the case of a constantly dragging disc brake causing noise your frame or fork
could be miss-aligned. In such a case you should contact your dealer who can care to this
with the MAGURA Gnann-o-mat disc optimizer for a totally even surface of the disc brake
mounts. These are absolutely necessary for a drag free function of your brake.
New brakes and/or new rotors or brake pads must always be run in by
braking at least 30 times from a speed of 30 km/h to achieve the maximum brake
power. Take your bike to a safe place to run in the brake.
Reach adjust is done with a 2,5 mm Allen key. Turning key clockwise: lever
blade moves away from the handlebar, turning counterclockwise: blade moves to the hand-
lebar.

Marta is a high-pressure system and comes with a reinforced hose, the
„MAGURA Disc Tube“ which will show this label. The Disc Tube needs an additional
insert for a proper fitting. Never mix and match either the hoses or other parts from
the other MAGURA disc brake models. Any misuse might cause serious accidents!
Never touch either the rotor or the brake caliper after long braking as this may
cause serious burns.
1. Remove the wheel so that you have free access to the brake caliper.
Push back both brake pads by putting the transport device or a flat blade screwdriver into
the gap. Move the screwdriver slowly back and forth until both caliper pistons are fully
retracted and flush with caliper body.
Never push back the pistons without the brake pads mounted! Open the brake
system only after having fully pushed back the brake pads.
2. Loosen the brake lever clamping screw with a 5 mm allen key. Turn the brake lever
and ensure that the reservoir is horizontal.
3. Slide the hose protection. Unscrew the sleeve nut on the brake lever with an
8 mm open-end wrench and pull the hose out carefully. Hold the hose carefully to avoid
any loss of oil! Do not squeeze the lever blade with the system open!
4. Put the hose on a workbench and shorten it with a sharp knife. The best tool is the
MAGURA cutter. Do not use saws or pliers!
6. Shorten the hose

THE PASSION PEOPLE
www.magura.com 11
Hold the hose carefully so that it cannot snap away (arrow)! Cut the hose squa-
rely! The sleeve nut can be re-used. The olive and the insert cannot be
reused and must be replaced!
5. Press manually a new insert into the hose until it is fully seated. Clamp the hose
into the groove of the mounting device as shown...
6. ...or clamp the mounting device as shown into a vice and hammer the insert careful-
ly into the hose.
7. Slide on the sleeve nut and a new olive onto the hose. Push the hose with the sleeve
nut and the new olive fully into the brake lever and tighten the sleeve nut with
an 8mm open-end wrench. Tightening torque: 4 Nm/ 34 in.lbs.
8. Always check for correct installation by pulling on the hose. Make sure that
the system has no leaks. Squeeze the lever blade, hold pressure and check hose con-
nections and the reservoir cover for eventual leaks.
Squeeze the lever blade several times (pump) to push the pads to their proper
position until the lever feel becomes very firm. If you cannot realize this, bleed the
brake (see page 15 onwards).

Brake Oil: MAGURA disc brakes use as transmission medium low viscosity mineral
oil, the biodegradable MAGURA ROYAL BLOOD. Contrary to DOT brake fluid the MAGURA
ROYAL BLOOD does not irritate human skin or strip the paint of your frame. Moreover it
does not absorb water like DOT and does not have to be changed regularly. What sounds
unbelievable is a fact: you can use your brakes over years without having to touch them
(except brake pad check and change!)
Always make sure that the brake system does not have any leaks by activating
the lever blade, holding it and checking the hose connections and reservoir cover for
eventual leaks. Consult a trained technician in case of leaks. Leaks cause poor bra-
king performance with possible serious accidents!
As to hints about repairs of the hose see page 14 onwards..
Brake pad wear: The brake pads are subject to wear due to friction between
rotor and pads. The Marta disc brake features a fully automatic pad wear adjust-
ment. Regularly check the thickness of your brake pads and replace them, if neces-
sary!
Control and replacement of the brake pads
Never touch either the rotor or the brake caliper after long braking as this may
cause serious burns.
Control of pads.
Squeeze the lever blade with the wheel mounted and hold pressure.
Hint: Use eventually a rubber band or a cable tie for this.
Check out whether the “finger” of the transport device fits in-between the “ears” of the
brake pads. On the picture on the left this is NOT the case, the pads must be chan-
ged! Minimum thickness of pads including holder is 2,5 mm. Change always both
pads simultaneously!
Here the “finger” of the transport device fits between the “ears” of the brake pads. The
pads are still o.k. Remember: the lever has to be pulled during this procedure!
Pad replacement.
1. Remove the wheel so that you have free access to the brake caliper.
Push both brake pads back by putting the transport device or a flat blade screwdriver into
the gap. Move the screwdriver slowly back and forth until both caliper pistons are fully
retracted and flush with caliper body.
Never push back the pistons without the brake pads mounted!
7. Maintenance, brake pad change

THE PASSION PEOPLE
www.magura.com 13
2. Remove the brake pad fitting screw with a 2 mm allen key.
3. Pull out the brake pads. Clean the pads with a dry rag that is free of oil and
grease.
Never push back the pistons without the brake pads mounted!
Never squeeze the lever blade without the brake pads in place and the wheel
mounted! If this happened by accident push back the pistons with mounted brake
pads by using the transport device or a flat blade screwdriver.
Use only genuine MAGURA brake pads! MAGURA cannot guarantee a correct
function of the brake if you use brake pads from other manufacturers, which were
not tested. Using other pads might cause poor braking and serious injury! All warran-
ty claims will be void in case of misuse!
4. Clean on the occasion of the brake pad change the brake body with a clean rag.
5. Mount the new brake pads. Make sure that the friction side of the new brake pads
points towards the rotor Tightening torque of the fitting screw: 1 Nm/ 9 in.lbs. Check
after installation the correct fitting of the pads by pulling them.
6. Check, whether the pistons are fully pushed back and whether the pads are flush
with the caliper body. Push the brake pads back with the transport device or a flat blade
screwdriver as described on page 12. Re-install the wheel and check for a correctly tighte-
ned quick release skewer of the wheel that should be mounted on the opposite side of
the caliper.
7. Squeeze the lever blade several times (pump) to push the pads to their proper positi-
on until the lever feel becomes very firm.
New brakes and/or new rotors or brake pads must always be run in by braking
at least 30 times from a speed of 30 km/h to achieve the maximum brake power.
Take your bike to a safe place to run in the brake.
Never contaminate brake pads with oil or grease this causing permanent loss of
brake power! Contaminated pads are definitely killed and must be replaced!

Disc brake service kit (code: 0721 294)
Don’t panic if the hose snaps! With the disc brake service kit and a separately available
spare hose (see spare parts pages 21/22), this can be repaired easily.
The Marta is a high-pressure system and comes with a reinforced hose, the
„MAGURA Disc Tube“ wearing also this imprint. The Disc Tube needs an additional
insert for a proper fitting. Never mix and match either the hoses or other parts from
the other MAGURA disc brake models! Any misuse might cause serious accidents!
1. Remove the damaged hose from both the brake lever and the caliper. Cut off the
barbed adapter (caliper connection) with a sharp knife. Slide both the sleeve nut and hose
protector on the other side. All mentioned parts can be re-used. Throw away the damaged
hose.
2. Prepare a new hose: Use only the reinforced „MAGURA Disc Tube“ hose!
One end this hose comes with a pressed fitting, which has to be screwed into the caliper as
described above. Tightening torque: 6 Nm/ 51 in.lbs.
Never shorten this hose at the end with the pressed fitting! You could no longer
use the hose then.
3. Tighten the prepared end of the new hose onto the caliper.
Tightening torque: 6 Nm/ 51 in.lbs.
4. Mount the brake hose as described in chapter 6.
After the installation of a new hose you will always have to refill the brake. The
following chapter 9 describes how the filling has to be done.
5. The new Marta is also compatible with the 90° hose fitting. Mounting as shown, also
see page 20.

Brake oil: MAGURA disc brakes use as transmission medium low viscosity mine-
ral oil, the biodegradable MAGURA ROYAL BLOOD. Contrary to DOT brake liquid the
MAGURA ROYAL BLOOD does not irritate human skin or strip the paint of your frame.
Moreover it does not absorb water like DOT and does not have to be changed regu-
larly. What sounds unbelievable is a fact: you can
use your brakes over years without having to touch them (except brake pad change!)
1. Loosen slightly the clamping screw of the brake lever with a 5 mm allen key and turn
the brake lever so that the reservoir is approximately 15° upwards from the horizon-
tal position. Slightly tighten the clamp screw in that position.
2. For filling and bleeding a MAGURA disc brake you will need the disc brake service kit
including all necessary tools.
3. Prepare the transparent filler tube by pushing in by hand the M6 barbed fitting
on which you have mounted an O--ring before. Put the other end of the filler tube on the
syringe and fill the syringe completely with MAGURA ROYAL BLOOD mineral oil. Fill the
syringe completely and make sure that there are no air bubbles inside. Turn the syringe
eventually to push out air bubbles.
4. Remove the brake pads as described on page 12 and slide the YELLOW transport
device as shown with its THICK END between the caliper pistons. Squeeze
slightly the lever blade (pump) to tighten the transport device.
5. Fix the caliper so that the hose connection is at the highest point of the caliper (hose
has to be positioned vertically!). It might be necessary that you have to unscrew the lower
caliper fitting bolt and to fix the caliper to realize this properly (e.g. on rearbrakes!) Unscrew
bleeding screw with a 3mm Allen key. Screw in the prepared syringe and tighten it by hand.
Place now a rag, which has to be free of oil or lubricants around the reservoir
and, more important, around the brake caliper. Care for a clean working environ-
ment! No dirt or particles may come into the brake system!
9. Filling and bleeding a brake

Español Italiano Nederlands Français English Deutsch
16
6. Remove ONLY the bleed screw of the reservoir with a 2,5mm Allen key. The reser-
voir cover and the membrane underneath remain on the brake lever!
7. Put the second syringe of the service kit WITHOUT PLUNGER into the opened drill
of the reservoir cover. Push oil from the brake caliper upwards until the oil column arrives in
the syring on the reservoir. You will see air bubbles now.
8. Now suck the oil carefully back with the filling syringe on the brake caliper. Make
sure that there is always enough oil in the reservoir syringe when you suck back the oil with
the filling syringe! You will see air bubbles again.
9. Actuate in addition CAREFULLY the lever blade to chase tiny air bubbles that might
hide within the system. The job is done when no air bubbles can be seen after having follo-
wed the steps above several times.
10. Before you remove the syringe on the reservoir make sure that there is only
a small quantity of oil inside. Place a rag around the brake lever and the caliper thus pre-
venting overflowing oil from dropping down and contaminating and killing the brake pads.
Remove the syringe and close the end that was inserted into the reservoir quickly with your
finger. Empty the remaining content of the syringe into an container.
11. Close the drill with the bleedscrew.Tightening torque: 1 Nm/ 9 in.lbs.
That’s it!
12. Remove the filling syringe and screw in the 5mm allen bleed screw.
Tightening torque: 2,5 Nm/ 22 in.lbs. Re-install the brake pads and the wheel.
Always pull the lever blade several times (pump) until the brake pads touch
the rotor. Always check for correct installation by activating the lever blade and
checking for eventual leaks. Never contaminate brake pads with oil or grease this
causing permanent loss of brake power! Contaminated pads are definitely killed and
MUST be replaced! A contaminated rotor can be cleaned with MAGURA brake cleaner,
warm dishwater or alcohol.

The XC disc brake wheel
There already exists enough literature concerning wheels, so just a few tips how
a well-built X-country disc brake wheel has to be.
Use spokes with a diameter of 2 mm (arc) / 1,8 mm which you cross three times.
No radial lacing with disc brake wheels!
Head-inside-spokes (=arc-outside-spokes have to be pulled, i.e. these spokes point forward
on the front wheel; on the back wheel these spokes point forward on the rotor
side and backwards on the drive side. All spokes have to be stressed equally and high.
Mount the quick release of the wheel on the opposite side of the caliper!
Never use ultra lightweight quick releases with titanium or aluminum axles for
your wheel sets in combination with a disc brake. You will not be in a position to rea-
lize the necessary tightening torque!

Use only genuine MAGURA accessories! Any parts manufactured by other

and approved by MAGURA and consequently nothing can be said about their short
and long-term function. Never use those parts! All warranty and product liability
claims will be void in case of misuse!
Never change the paint, the finish or the consistence of your brake. This might
cause total failure of the whole system with possible heavy bodily injury!
13. Warranty
MAGURA is giving a 5-year leakproof warranty on brake levers (master
cylinder) and brake calipers if you register your brake online on magura.com. Watch out

the following:
abuse
mixing and matching the brake with parts from other manufacturers

We expressly point out that a warranty claim is only accepted with a
clear proof of purchase (payment receipt of the dealer!) and recommend
