2 Remove the clevis pin and disconnect the
pushrod from the brake pedal. Note that on
models with a vacuum servo unit the pushrod
is on the lower hole, whereas the upper hole is
used for models without a servo unit.
3 Unscrew the self-locking nut from the pivot
bolt, pull out the bolt and lower the brake
pedal. Note that on non-servo models a return
spring is also fitted to the pedal.
4 Examine the pedal bushes for wear and
renew them if necessary.
Refitting
5 Refitting is a reversal of removal, but lightly
grease the bushes and clevis pin and renew
the self-locking nut.

and refitting
2
Removal
1 Move the front seats fully forward then
remove the screw and lift the cover from the
handbrake lever.
2 Fully release the handbrake then unscrew
the adjustment nut on the rear of the cable
compensator until both cables can be
unhooked.
3 Unbolt and remove the handbrake lever
assembly from the floor (see illustration).
Refitting
4 Refitting is a reversal of removal, but adjust
the handbrake, as described in Section 15 on
completion.
19 Anti-lock braking system
(ABS) - general information
From 1991, the Bendix anti-lock braking
system is available as an option on certain
models.
The system is fail-safe, and is fitted in
conjunction with the conventional braking
system, which allows the vehicle to retain
conventional braking In the event of a failure
in the ABS system.
To prevent wheel locking, the system
provides pressure modulation in the brake
circuits. To achieve this, sensors mounted at
each front wheel monitor the rotational
speeds of the wheels, and are thus able to
detect when there is a risk of wheel locking
(low rotational speed). Solenoid valves are
positioned in the brake circuits to all four
wheels and the solenoid valves are
incorporated in the regulator unit, which is
controlled by an electronic control unit. The
electronic control unit controls modulation of
the braking effort applied to each wheel,
according to the information supplied by the
wheel sensors.
Should a fault develop in the system, a
self-diagnostic facility is incorporated in the
electronic control unit, which can be used in
conjunction with specialist diagnostic
equipment available to a Peugeot dealer to
determine the nature of the fault.
The brake components used on models
fitted with ABS are similar to those used on
models with a conventional braking system.
Rear disc brakes are fitted to all
ABS-equipped models, and all procedures for
the rear brake and handbrake components
are as described for 1.9 GTI models in the
relevant Sections of this Chapter.

Warning: It is strongly
recommended that any work
involving components of the
braking system on a vehicle
equipped with ABS is entrusted to a
Peugeot dealer, who will have the
necessary specialist knowledge and
equipment to carry out the work safely and
effectively.
Regulator unit
1 At the time of writing, no information was
available regarding removal and refitting of
the regulator unit.
Wheel sensor
Removal
2 The wheel sensors are mounted in the rear
of the hub carriers. To remove a wheel sensor,
proceed as follows.
3 Disconnect the battery negative lead.
4 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and vehicle support”). Remove
the roadwheel.
5 Carefully pull the sensor wiring from its
retaining clips, and working under the wing,
disconnect the sensor wiring connector.
6 Unscrew the securing bolt, and withdraw
the sensor from the hub carrier.
Refitting
7 Refitting is a reversal of removal, but ensure
that the front face of the sensor is perfectly
clean, and ensure that the wiring is correctly
routed. Clean the sensor securing bolt
threads, then apply suitable thread-locking
fluid and tighten the bolt securely.
Electronic control unit
Removal
8 The electronic control unit is located on the
left-hand side of the luggage compartment.
To remove the control unit, proceed as
follows.
9 Disconnect the battery negative lead.
10 Open the tailgate, and carefully pull the
trim from the left-hand side of the luggage
compartment to reveal the control unit.
11 Unscrew the securing nuts, and withdraw
the cover from the control unit.
12 Disconnect the control unit wiring plug.
13 Unscrew the securing nuts, and withdraw
the control unit from its mounting bracket.
Refitting
14 Refitting is reversal of removal.
