### Removal Procedure

Caution: Avoid taking the following actions when you service wheel brake parts:

• | Do not grind brake linings.

• | Do not sand brake linings.

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.
