Removal
Note!
^
For the removal and installation of the hydraulic unit -D- the brake master cylinder -B- and the brake booster -C- remain mounted (installed).
1. Switch off ignition. Remove cover -A- from the hydraulic unit/brake unit.
2. Hold down brake pedal with pedal holder, so that the brake fluid does not run out of the expansion tank completely.
3. To remove the hydraulic unit -D-, carry out the following removal procedure:
-
Undo the brake lines on the hydraulic unit.
-
Remove the lines between the brake master cylinder intermediate piston circuit and the hydraulic unit.
-
Close the brake lines and the brake line connections with suitable plugs.
-
Disconnect plug from pressure sensor (vehicles with PSM).
-
Unlock/disconnect the control module connector on the hydraulic unit. Cover the plug connection and the plug!
Note!
^
In the case of assembly work on the hydraulic connections, the electrical plug connections on the hydraulic unit must always be connected!
^
This prevents the plug connections on the hydraulic unit or in the plugs inside from being splashed with brake fluid or water!
^
Any damp plug must be wiped dry before being disconnected from the plug on the hydraulic unit!
^
Brake fluid on electrical contacts (even thinned brake fluid) leads to corrosion and may cause faults in the system!
-
Undo and guide out the hydraulic unit. In the case of unfavorable tolerances, remove the hydraulic unit without the bracket for the hydraulic
unit.
