Removal
NOTE: For the removal and installation of the hydraulic unit -D-, the brake master cylinder -B- and the brake booster -C- remain fitted (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.
-
Pull off pressure sensor plug.
-
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.
