3.1. Brake system
3.1.1. Air couplings
The main connection between the truck
and trailers is air couplings.
Generally, 3 different types of air cou-
plings are used in the trailers. These 3
types of air couplings have the same
function but with different shapes and
connections. There are 2 different air
supply lines in the system.
•Brake Line (Yellow)
•Supply Line (Red)
Service Line: It is the pneumatic line
where the pneumatic brake signal from
the truck is transmitted.
Supply Line: It is the pneumatic line
where the compressed air needed by the
trailer is transmitted from the truck.
According to the type of vehicle, your ve-
hicle can be equipped with one or two
different types of air couplings.
•Standard Couplings (Palm)
•Duomatic Coupling
•C (UK) Couplings

13 / 84
If your vehicle is equipped
with 2 different types of coup-
lings, you must use only one
type at the same time.
When the couplings are
mounting/demounting, the
parking brake of the truck and
trailer must be engaged.
If the brake parameters are
modified, your vehicle's brake
calculation might be non-sui-
table for regulations. Only aut-
horized services must service
to the EBS modulator.
Only authorized services and
personnel should make servi-
ce operations for the brake
system.
There might be test points on the chassis
or above the air couplings. When you re-
move the test points rubber protection
parts and push the points you can check
the air pressure on the brake lines.
One of the test points is the
service line. As long as there
is no brake signal from the
truck side, this line will be
empty, there will be no air at
the test point. The other test
point is the brake air tubes li-
ne. From this test point, it can
be checked whether there is
air in the vehicle.

couplings are matched correctly.
•First mount service line yellow (1).
•Mount supply line red (2).
3.1.1.2. Demounting of Standart
(Palm) Couplings
•The coupling which comes from the
truck should be pushed slightly from
the lower side to the upper side and
demount the coupling.

•First demount the supply line red
(2).
•Demount the service line yellow (1).
•Slightly slide plastic covers to the
lower side and close the plastic
covers.
Closing the coupling
Driving with a non-suitable air
connection is dangerous and
forbidden.
Using damaged air supply
parts can cause serious ha-
zards. Torn or damaged comp-
ressed air connectors reduce
the vehicle's braking
performance.
3.1.1.3. Mounting of C (UK) Couplings
C (UK) couplings
•Be sure that sealing surfaces are
clean and durable. If necessary,
clean/change the air coupling.

3.1.1.7. The Connections In Vehicles
That Gooseneck and Platform Area
are Separate
Hydraulic multi quick coupling
EBS connection
For vehicles whose platform area is sep-
arated by a gooseneck, the hydraulic
quick coupling and all electric sockets
must be removed before the separation
process.
The hydraulic quick coupling and all
electric sockets, which were removed on
the vehicle whose loading operation has
been completed and whose gooseneck
and platform area are matched, must be
installed correctly.
If the gooseneck and platform
area is matched, the vehicle
will not brake properly if the
vehicle is driven without the
EBS power cable attached.
In the vehicle whose goose-
neck and platform area are
matched, the vehicle cannot
be moved without the Duoma-
tic coupling attached, the par-
king brakes will be activated.
3.1.2. Compressed Air Tanks
Pressured air can be stored in the air
tanks.
The quantities and capacities of the air
tanks can be changed according to your
vehicle specifications.
In cold periods of the year or when the
air humidity is high, the moisture in the
air can be condensed and collected in
the compressed air tank.
The trucks are generally fitted with air
driers to prevent condensation in com-
pressed air. The trucks are generally fit-
ted with air driers to prevent
condensation in compressed air. Even if
the air driers system, the humidity in the
air can be condensed. The condensed
water must be drained out via the drain
valve.
The water in the air tanks should be
completely drained out. That's why
please push the valve on the air tanks.
Air Tank
1. 1.Compressed Air Tanks

2. 2.Drain valve
The water in the compressed
air tank can cause corrosion
problems and affect the func-
tionality of the brake system.
The frozen water in the pneu-
matic lines can cause the fai-
lure of the brake system.
The water in the pneumatic
system should be checked
more frequently in cold weat-
her or extremely variable out-
side temperatures.
When the air tank pressure is
lower than 4,5 bars, the EBS
warning lamp on the truck
turns on and the driver can
see this situation.
When the pressure in the ser-
vice line (in the yellow coup-
ling) is lower than 2,5 bars,
the brakes automatically lock.
3.1.3. EBS Socket
EBS Socket
Our trailers and semi-trailers are
equipped with an EBS system.
EBS is an electronically controlled brake
system, that is fitted with automatic load
sensing braking pressure regulation
(ALB) and automatic anti-skid systems
(ABS/ABV).
To activate the EBS system, your truck
and trailer must be equipped with an
EBS system. Please mount the EBS ca-
ble that will come from the truck to the
EBS socket on the trailer.
•Driving with a non-connected EBS
connection is illegal.
•Drive only with an approved and
well-operating EBS plug connection
in accordance with regulations.
•EBS connection must be made be-
tween the truck and trailer.
•Verify the EBS plug connection with
a system check (the solenoid valves
in the EBS modulator are activated
and briefly activated and deacti-
vated for 2 seconds after "ignition
on").
When the truck engine is activated and
during the travel, the EBS system will be
checked automatically. If the truck
screen is suitable/adjusted, the EBS fail-
ures will be shown with the EBS mistake
lamp.
The EBS mistake lamp on the truck
screen will be turned on when the igni-
tion key is activated. If there is no failure
on the EBS system, the lamp will be
turned off in appr. 2 seconds.
After 7 km/hours speed, If there is a fail-
ure on the EBS system (Sensor mistake
and etc.) EBS lamps will be flashed.
If the EBS lamp is activated, please con-
tact with authorized services
immediately.
The trailers equipped with a
Trailer EBS E braking system
may only be used with trac-
tors with:
•ISO 7638-1996 connectors (ABS +
CAN) or ISO 7638, 7 pin with CAN
data line (EBS Truck)

17 / 84
Even if the truck 7 pin socket
(ISO 7638) has a CAN data li-
ne, if the spiral cable used bet-
ween the truck and the trailer
is 5-core, it will cause the trai-
ler EBS Modulator to not work
properly. For this reason, a 7
core spiral EBS patch cable
should always be used.
If you drive without EBS con-
nectors or if there is a prob-
lem on the EBS system, the
brake system will not be wor-
ked properly. This situation
may cause an accident.
Trailers are equipped with an
additional power supply for
the EBS system. Thanks to
the extra power supply from
brake lamps, when the EBS
connector is damaged, an ex-
tra safety function will be acti-
vated. The EBS system will be
fed from brake lamps and ALB
(automatic load sensing bra-
king pressure) and ABV (anti-
skid system) functions will be
activated.
3.1.4. PREV ( Park Release Emer-
gency Valve )
Generally, brake control systems will be
located on the driver's side. It may be dif-
ferent on your vehicle according to the
vehicle's construction.

3.1.4.1. Service Brake
Black button

The black button is located under the
marked area in the image below.
The location of black button
Thanks to the service brake, the trailer
can be made maneuvers without air con-
nections. The black button can be used
only without semi-trailer air supply (red)
connections on the trailer.
When you push the black button, the
service brake will be disabled. When you
pull the black button, the service brake
will be activated.
If the service brake is used a
lot of times, without an air
connection, air pressure in
the system and braking power
may reduce.
When the air connections are de-
mounted, the service brake will be auto-
matically activated. When the air
connections are mounted, the service
brake will be automatically disabled.
The service brake is not sui-
table for braking of the semi-
trailer permanently. During
longer waiting periods, the se-
mi-trailer must be secured
with a spring-loaded park bra-
ke and with wheel chocks.
3.1.4.2. Park Brake
Spring loaded park brake
Spring loaded park brake control button
is used for longer parks of semi-trailers
with or without truck on plain or inclined
lands.
It is a spring force based brake. It does
not need air for braking. When the air
tube pressures of the trailer fall below
2.5 Bar, it is automatically activated and
the brake is activated with the spring
force.
When the red button is pulled, spring
loaded park brake will be activated.
When the operator push the red button,
spring loaded park brake is deactivated.
If the trailer air tubes are empty, the
brake cannot be disabled even if the but-
ton is pressed.
This brake will not be deacti-
vated automatically. Before
driving, the operator must
deactivate the brake.
3.1.5. Brake Chambers
Your vehicle may be equipped with disc
or drum brake axles according to your
choice. For both brake types, the brake
chambers are going to use for braking.
The brake chambers will be chosen

19 / 84
according to axles type and loading ca-
pacity. The maintenance, modification or
repair operations must be performed by
authorized services.
3.1.5.1. Manually Deactivation of
