Removal





Note:
^ For the removal and installation of the hydraulic unit -D-, the booster pump -A- of the brake master cylinder -B- and the brake booster -C- remains 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 plug on the hydraulic unit. Cover the plug connector 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.
