The prevention

Elements of a hydraulic control system of coupling (the main cylinder, the working cylinder and connecting hoses) represent uniform knot and cannot be divided.

Access to the main cylinder is extremely limited. Peugeot recommends use of the special tool (0216J). It is possible to use накидной a wrench with the cut groove to put on it a hose.


1. Disconnect the negative plug of the accumulator.
2. In car salon open a cover of an immobilizer and turn on 90 a clamp of a cover of a box with fuses. Disconnect an electric socket from колодки, unscrew screws of fastening and remove the bottom panel from outside the driver.
3. Remove the air filter and the inlet air channel.
4. Remove the spherical hinge of a pusher of the main cylinder from a coupling pedal.
5. In a motor compartment remove a tank of the main cylinder of coupling from a partition.
6. Using special tool Peugeot or накидной a key with the cut groove, turn the main cylinder on 90 clockwise and remove it from a partition.
7. Remove the working cylinder (1), having pressed it (2), and in this position having turned on 90 counter-clockwise (3).
8. Take a hydraulic hose from скоб fastenings and take all knot from a motor compartment.


The prevention

On new knot the pusher of the executive cylinder is closed by a plastic cover which is broken off by the first pressing a coupling pedal. Do not try to remove this cover before pusher installation in a pedal since at work the pusher can jump out of a pedal nest.

1. Press a pedal of coupling and keep it in this position.
2. Establish the main cylinder of coupling, combining a white label on the cylinder with a corresponding white label on a partition. Using special tool Peugeot, press and turn the cylinder on 90 counter-clockwise before its accurate fixing.
3. Establish a tank of the main cylinder on a partition.
4. Grease the working end of a pusher of the executive cylinder with greasing on a basis дисульфида molybdenum and establish the working cylinder into place, having moved and in this position having turned it on 90 clockwise.
5. Fix a hydraulic hose скобами in a motor compartment.
6. Grease the spherical hinge of a pusher of the main cylinder, then lift a pedal of coupling and connect to a pusher.
7. Slowly press a pedal of coupling and slowly manually lift it back. In 10 seconds repeat this operation and check up that the pedal normally comes back in a starting position.
8. Establish earlier removed elements in the bottom part of the panel and connect the accumulator.
