. Don’t overestimate your technical capacities. This brake system must be fitted
by a competent cycle mechanic using the correct tools. Incorrect installation
could result in brake failure that could cause serious or fatal injuries.
. Please refer to the website videos and technical documents for more informa-
tion including servicing and maintenance - www.hopetech.com / Tech support
section.
The video logo indicates you can find some useful tips on the website
. This brake system has been designed to be used only on two-wheel vehicles
with human propulsion. Any other application is not advisable and could result
in the failure of this product.
. Your brake system will generate heat during braking. Never touch either the
disc or caliper after long braking period as this could cause severe burns.
. Before each ride always check the brake for proper function, the brake pad for
wear and that there is no system damage resulting in fluid leaks.
. It’s common sense to also check that your wheel’s quick release systems are
securely installed and tightened.
. Your braking performance will improve in almost all conditions. Please take
time to become familiar with your new brake. Always ride within your own
ability.
. Brake pad contaminated with brake fluid, chain lubricant or unsuitable bike
cleaner will need replacing because the overall brake performance will be
greatly diminished.
. If you have any doubts or questions please contact your dealer or the appropri-
ate distributor for your country.
. If you decide to ignore these important safety warnings and instructions, you
are doing so at your own risk and Hope Technology cannot be held responsible
for any consequences resulting of the misuse of the brake system.
TOOLS REQUIRED
+ Torx T25 driver
+ 5mm Allen key
+ 4mm Allen key
+ 8mm spanner
+ Flat blade screw driver
+ Easy Bleed kit (not compulsary but helpful)
Once again, don’t overestimate your technical skills. If you are not familiar with
this sort of installation we advise that this brake system should be fitted by a
competent cycle mechanic.
INTRODUCTION
BOX CONTENTS
Congratulations, you have just acquired an highly versatile and powerful HOPE
hydraulic disc brake system proudly made in our Barnoldswick factory in Great Britain.
The new TECH3 Duo master cylinder associated with the X2, E4 or V4 caliper will suit
any riding style from XC to DH.
The new TECH3 Duo master cylinder has been designed so you can operate the
front and rear calipers from one single side only, 2 fingers from one hand to control
each brake independently. The construction is derived from the proven TECH3 master
cylinder. With the finger reach and bite point adjustments on each lever, you can be
sure the levers will feel comfortable and suit your riding style. It also features a split
clamp for easy fitting, integrated reservoir for easy bleeding and SRAM shifter direct
mount options.
The TECH3 Duo master cylinder is only compatible with the following Hope
Technology calipers: X2, E4 and V4.
Throughout the range the rotors are available from Ø140mm (rear only) to
Ø220mm, for 6 bolt IS fittings. We’d recommend to use a smaller rotor/caliper
with the brake associated with the longer lever.

INSTALLATION STEPS
fig 2 fig 3
5. CENTRALISE THE PADS OVER THE DISC
=
=
pad
pad
rotor
This step is very important and mustn’t be ignored.
Gently pump the lever in order to bring the pads closer to the disc. One pad might
enter in contact with the disc before the other. If this happens, hold the disc against
the pad that is already in contact with the disc to allow the other one to move.
For an optimised lever feel, both pads must enter in contact with the disc at the
same time and allow the same clearance (see arrows) when retracted. The disc
should not be flexing at any time.
1. CONNECTING THE MASTER CYLINDER TO THE CALIPERS
2. ATTACHING THE LEVER TO THE BARS
3. ATTACHING THE CALIPER TO THE FORK OR FRAME
3.1 MOUNTING THE CALIPER ON POSTMOUNT TYPE MOUNTS
=
=
fig 1
Note : We do not recommend pumping the lever to push pads out to align caliper
at this point. See section 4 regarding the alignment of pistons.
To ensure that the caliper is properly aligned and to help avoid squealing or bad lever
feel - prior to fitting the brake, it is important that the tabs of your fork or frame are
clear of any paint or burrs.
Only follow these steps if the calipers have been purchased separately and not
already installed on the bike.
The HOPE calipers are postmount type. You will therefore need to use an
adaptor bracket to fit it on IS brake mounts or using a different size rotor.
a) Attach the master cylinder assembly
to the handlebars. When you are happy
with the orientation of the lever, tighten
alternately the M5 clamp bolts using a
4mm Allen key. Recommended tighten-
ing torque : 4-5 N.m.
b) If not already in place, route the hose
and caliper down to the fork brake mount
or along the frame to the rear brake
mount.
3.2 MOUNTING THE CALIPER ON IS TYPE MOUNTS
On IS mount you will have to use an adaptor bracket to be able to fit the brake
caliper.
a) According to the rotor size and type of mounts, attach the suitable adaptor
bracket onto the brake tabs and tighten the two M6 bolts using a 5mm Allen key.
Recommended tightening torque 8-9 N.m. Illustration fig 2.
b) Follow the same instructions as fitting the brake onto a postmount (see
previous section). Illustration fig 3.
Avoid situations that could
damage the brake hose and/or
your bike frame and components

BREAK IN PERIOD AND MAINTENANCE
Before riding and before every ride, check the correct action of the brake and that
braking effort is applied as the lever is pulled.
To achieve the maximum braking performance, the new pads will need bedding in.
Please note that sintered pads take longer to bed in than organic pads.
To bed in the pads, ride a short distance whilst alternatively gently applying the
brake on and off without attempting to stop. This procedure will achieve good
braking performance but will reach its full potential after a few rides.
About maintenance tips refers to our “how to” videos on the website.
To optimise the performance of the brake it is important to keep the caliper pistons
lubricated using silicon lubricant only. We advice doing this at least at every pad
replacement.
For brake bleeds use only dot 5.1 or dot 4 brake fluid from a clean container.
First connect each caliper to the master cylinder using Hope hydraulic hose and
connectors.
The rear caliper must be routed to the lower cylinder controlled by the longer lever.
For cleaner hose routing you may swap a straight connector and use the 90° connec-
tor provided.
4. BLEED THE BRAKE SYSTEM
Use only DOT4 or 5.1 brake fluid and wear adequate protective equipment such as
nitrile gloves and safety glasses.
To bleed the system proceed as bleeding a Tech3 brake system.
Refer to the How to video in the technical section of our website.
Using Hope Technology Easy Bleed kit would facilitate the task but is not compul-
sory.
Proceed individually with each caliper making sure the reservoir lid is level before
opening it. Typically, you’ll need to spin the master cylinder 180° to bleed the rear
brake.
a) Before attaching the caliper ensure that the brake pads are
fully retracted in the caliper. If not, gently push the piston back
using a plastic tyre lever or something similar. Beware
not to damage the pads. Take them off if necessary. Push
on the left hand side pad backplate to push the right hand
side piston and vice versa.
b) Mount the wheel fitted with the rotor, ensuring
correct fitment in dropouts.
c) Position the caliper on the mount and slightly tighten the
two M6 bolts.
d) At both front and rear of the caliper, adjust its position
so it is central over the rotor (see arrows on fig 1) then tighten
the two M6 bolts using a 5mm Allen key. Recommended
tightening torque 8-9 N.m.

PERSONAL SETTINGS
The TECH3 lever allows two types of personal adjustment to fit all preferences.
The Bite Point adjustment : This will modify the free stroke of the lever blade
before the pads enter in contact with the disc. With your fingers, turn the bite point
adjuster knob clockwise to reduce the free stroke and anti-clockwise to increase the
Finger reach adjustment : This refers to the position of the lever blade relative
to the bars. After adjusting the bite point, you will need to set or re-set your lever
reach as it will change when adjusting the BPC.
With your fingers, turn the adjuster screw clockwise to increase the reach and anti-
clockwise to reduce it.
Bite point adjuster knob Reach adjuster knob
The Tech3 Duo levers are easy to set if you note the following steps:
1- first adjust the bite point on the long lever
2- adjust the reach on the long lever
3- adjust the bite point on the short lever with the same setting as the long lever
4- adjust the reach of the short lever with the same setting as the long lever then
add 3 click clockwise
Note : you made need to reproduce each step several times before reaching your
optimum setting.
