Preliminary Procedures

1. Inspect the fluid level in the brake master cylinder reservoir.

2. If the brake fluid level is midway between the maximum-full point and the minimum

allowable level, no brake fluid needs to be removed before proceeding.

3. If the brake fluid level is higher than midway between the maximum-full point and the

minimum allowable level, remove brake fluid to the midway point before proceeding.

4. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .

5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and

Installation .

CAUTION:

Refer to Brake Dust Caution .

NOTE:

Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its
mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this
manner will cause the flexible brake hose to bear the weight of the caliper, which may cause
damage to the brake hose and in turn may cause a brake fluid leak.
