Brake fluid pipes and hoses - removal and refitting

Caution: Refer to the precautions in Section 1.

Removal
1 To remove a flexible hose, always free it from any mounting bracket(s) first by prising out the U-shaped retaining clip, and then using two close-fitting spanners to disconnect the hose-to-rigid pipe union (see illustration).

2 Once disconnected from the rigid pipe, the flexible hose may be unscrewed from the caliper or wheel cylinder union, as applicable.

Refitting
3 When reconnecting pipe or hose fittings, note that the seal is made at the swaged end of the pipe, so do not continue to tighten a union if it is tight, yet still stands proud of the surface into which it is screwed.

4 A flexible hose must never be installed twisted, but a slight “set” is permissible to give it clearance from adjacent components.

This can be achieved by turning the hose slightly before fitting the U-shaped retaining clip to the mounting bracket.

5 Rigid pipelines can be made to pattern by motor factors supplying brake components.
