Removal Procedure

Some models or aftermarket brake parts may contain asbestos fibers which can become airborne in dust. Breathing dust with asbestos fibers may cause serious bodily harm. Use a water-dampened cloth in order to remove any dust on brake parts. Equipment is available commercially in order to perform this washing function. These wet methods prevent fibers from becoming airborne.

Siphon 2/3 of the fluid from the master cylinder reservoir.

Inspect the 2 brake pad retainers for the following conditions:
- Sufficient rebound
- No deformation
- No cracks
- No wear
- No rust
- No dirt
If the retainers meet the above conditions, the retainers can be used again.
