ABS: Precautions for the repair
38C
I - SAFETY
- If a lift must be used for an operation, respect the
safety instructions (see Vehicle: Towing and lifting)
(02A, Lifting equipment).
- Protect any bodywork components which could be
damaged by brake fluid with covers.
- to ensure there is no risk of sparks, do not place any
metallic objects on the battery.
- Brake fluid is highly corrosive. Carefully clean any
brake fluid spilt on parts of the vehicle.
II - CLEANLINESS
- Clean around the braking system with BRAKE
CLEANER (see Vehicle: Parts and consumables
for the repair) (04B, Consumables - Products).
- If a component is being replaced by a new one, do not
remove the new component from its packaging until its
is ready to be fitted onto the vehicle.
III - GENERAL RECOMMENDATIONS
- During an operation which requires the braking circuit
to be opened, position a pedal press on the brake
pedal to limit the outflow of brake fluid.
- After any operation on the ABS, it is essential to con-
firm the repair with a road test and a check using the
Diagnostic tool.
1 - Yaw speed and lateral acceleration sensor
The sensor must be fitted facing the vehicle's direction
of travel (as shown by the arrow).
Be sure to replace any sensor which has sustained an
impact.
2 - Hydraulic unit
3 - Wheel speed sensor
4 - Brake servo
Equipment required
pedal press
Diagnostic tool
WARNING
Prepare for the flow of fluid, and protect the sur-
rounding components.
WARNING
Switch off the vehicle ignition so as not to activate
the hydraulic unit solenoid valves when bleeding the
brake circuit.
WARNING
To ensure that the wheel speed sensor works prop-
erly, do not mark the sensor target on the bearing.
WARNING
In order to prevent irreversible damage to the front
hub bearing:
- Do not loosen or tighten the driveshaft nut when
the wheels are on the ground.
-Do not place the vehicle with its wheels on the
ground when the driveshaft has been loosened or
removed.
IMPORTANT
To avoid breaking the connection between the
brake servo pushrod and the brake pedal, check
that the safety clevis pin is locked onto the brake
servo pushrod by tilting it from the top downwards.
