CHECK - ADJUSTMENT LOAD SENSITIVE BRAKE COMPENSATOR

1 - SPECIAL TOOLS

[1] Braking pressures checking equipment (-).0808-ZY .

[2] Pressure take-off unions .

[3] Brake fluid reservoir filler cap (-).0810 .

[4]Set of FACOM 470 type circlip pliers .

[5] CMBB-T 935 R type pressurising equipment .

2 - PRELIMINARY OPERATIONS

Place the vehicle on a four post lift (To make the operation easier) .

Check that there are no hydraulic leaks .

Check that none of the pipes are kinked .

Remove any object from the vehicle which may weigh more than 10 kg .

3 - SETTING UP THE TOOLS

Selection of pressure adaptor connectors [2] .

| diameter and pitch of the bleed screws
--- | ---
front wheel | M7 x 100
rear wheel | M7 x 100 (drums without ABS - discs) M8 x 125 (drums with ABS)

4 - PRESSURE SYMMETRY CHECK

4 - 1 - CONNECTIONS

Connect the pressure take-off unions [2] in place of the bleed screws, then the pressure checking equipment [1] .

NOTE : the longest hose must be connected to the rear wheel on the passenger's side .

Position : The filler cap [3] .

Pressurise the brake circuit using the tool [5] .

NOTE : it is also possible to carry out a manual bleed (using the pedal) .

Bleed : The pressure measuring equipment [1] (See instructions for use) .

4 - 2 - CHECK

Start the engine .

IMPERATIVE : press the brake pedal gradually .

Check that the pressure of the rear wheels is equal .

Permissible pressure difference : ± 4 bar(s) .

If the pressure difference is within the tolerance: check the braking distribution .

If the pressure difference is outside the tolerance: replace the compensator .

Remove the union [2] from the rear wheel on the driver's side .

Refit the bleed screw and bleed the circuit .

5 - CHECK - ADJUSTMENT BRAKING DISTRIBUTION

NOTE : carry out the operation: Pressure Symmetry Check before carrying out any of the following operations .

5 - 1 - CONNECTIONS

Connect the pressure take-off union [2] to the front wheel on the driver's side .

Connect the hose of the tool [1] to the union [2] .

Bleed :

- the pressure measuring equipment [1] (see instructions for use)

5 - 2 - CHECK - ADJUSTMENT

Read the recommended values by referring to section: Braking Distribution Check Values .

On the vehicle, engine running, read the rear pressure for a front pressure of 60 bars .

IMPERATIVE : the check pressure must be obtained by pressing gradually on the brake pedal .

Compare the value read (table/vehicle) .

If the rear pressure is correct for a front pressure of 60 bars :

- read the rear pressure for a front pressure of 100 bars

If the rear pressure is correct for a front pressure of 100 bars :

- the distribution is correctly adjusted

If the rear pressure is incorrect for a front pressure of 100 bars :

- replace the brake compensator

If the rear pressure is incorrect for a front pressure of 60 bars :

- carry out the following operations

The hole (B) enables fitting of the tool [4] .

Fit the tool [4] .

Slacken the bolt (1) .

Move the spring rod :

- towards the rear to increase the pressure
- towards the front to reduce the pressure

Tighten the bolt (1) to 1.3 da.Nm .

On the vehicle, engine running, read the rear pressure for a front pressure of 60 bars .

Compare the value read (table/vehicle) .

Repeat these adjustment operations until the recommended pressure is obtained .

In order to check the correct operation of the compensator, read the rear pressure for a front pressure of 100 bars :

- if the value(s) are outside the limits, replace the compensator

After repair :

- remove the checking equipment [1]
- bleed the brakes
- carry out a road test

6 - BRAKING DISTRIBUTION CHECK VALUES

6 - 1 - EXAMPLE

example(s) of reading(s)
shape | 5-door
--- | ---
engine type (legislation type) | DW10 TD (RHY)
type of braking | ABS
wheel diameter | R14
fuel level | fuel tank 1/4
option(s) (sun roof - towbar) | sun roof

The distribution values which correspond to this reading example are as follows :

- rear pressure - for a front pressure of 60 bars : 32 + 1 = 33 bar(s)
- rear pressure - for a front pressure of 100 bars : 42 + 1 = 43 bar(s)

WARNING : values are expressed in bars with a tolerance of : ± 2 bar(s) .
