Replacing vacuum hose for brake booster

Necessary preliminary work: 

Attention! 

Before beginning work, fully press the brake pedal several times to reduce the vacuum pressure in the brake servo. This makes it easier to pull off the vacuum hose.

Unlock quick-release fastener (1) and pull out vacuum line (2).
