34 33 071 Replacing Vacuum Hose For Brake Booster (N52K)
WARNING: This page is about a different car, the 2010 BMW X5, 2009 BMW X5, 2008 BMW X5, and 2007 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
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 vacuum hose. Vacuum hose and non-return valve are welded together and are replaced together as a single unit.
Necessary preliminary tasks:
- Read and comply with General Information. See General Information
- Remove left partition wall for equipment compartment
Detach partition wall seal upper section (1) in direction of arrow.
Remove non-return valve (2) from brake booster.
Installation:
Check seal for non-return valve and replace if necessary.
Unlock quick-connect coupling (1) and detach vacuum line.
