Replacing Vacuum Hose for Brake Booster

34 33 071 - Replacing vacuum hose for brake booster (M54)





Necessary preliminary tasks:
- Read and comply with General Information Service and Repair.
- Remove left partition wall for equipment compartment.

Important!
Before beginning work, fully press the brake pedal several times to reduce the vacuum pressure in the brake booster. This makes it easier to remove the non-return valve.
- If a rubber vacuum hose is fitted, it can be replaced individually.
- If a plastic vacuum line is fitted, it can only be replaced as a single unit together with the non-return valve.





Release hose clip (1) and detach vacuum hose (2).

Installation:
Replace hose clip.
