Removal and installation the brake hose (Audi A4 B6)

The master cylinder and the four wheel brakes are connected to each other by rigid brake lines and strong flexible brake hoses. Work with metal brake lines should be left to a workshop, as a lot of experience is needed to install them correctly. If the brake hoses are damaged, they can be replaced by yourself. During installation, the hoses should be secured at the same points where they were originally secured.

1. To remove the hose, unscrew the union nut of the corresponding brake pipe. Make sure that the pipe does not get twisted.

2. Some brake hoses are secured with a special holder to prevent them from slipping on the body (sheet metal staples). When installing, do not forget to install this holder!

3. When installing, first screw the hose in the place where the external thread is located, and only then tighten the second threaded connection.

4. The hose should not twist around its axis. The correct position of the hose can be determined by the solid colored strip running along the hose, the rubber lug or the rubber profile.

5. Remove air from the brake system.

6. Be sure to check whether the hose rubs against adjacent parts when driving. If necessary, move the spacer. Repeat the check after a long trip.
