- Inspect the fluid level in the brake master cylinder reservoir.
- If the brake fluid level is midway between the maximum-full point and
the minimum allowable level then
no brake fluid needs to be removed from the reservoir before proceeding.
- If the brake fluid level is higher than midway between the maximum-full
point and the minimum
allowable level then remove brake fluid to the midway point before
proceeding.
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle
.
- Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and
Installation .
- Grasp the brake caliper housing and try to move the brake caliper
housing up/down and forward/reverse
in relation to the brake caliper mounting bracket (3). If excessive
looseness is observed the brake caliper
bracket bushings and/or the brake caliper mounting bolts may need to be
replaced.
- Compress the front caliper pistons.
- Install a large C-clamp over the top of the caliper housing and against
the back of the outboard pad
(1).
- Slowly tighten the C-clamp until the pistons are pushed completely into
the caliper bores.
- Remove the C-clamp from the caliper.
- With the pistons compressed into the caliper bores, grasp the brake
caliper housing and slide it back and
forth on the brake caliper mounting bolts. Check for smooth operation. If
the brake caliper housing slide force is high or the
brake caliper housing does not slide smoothly, inspect the brake caliper
mounting
bolts and/or the brake caliper mounting bracket bushings for wear or damage.
If wear or damage
conditions are found, replacement of the brake caliper mounting bolts and/or
the brake caliper mounting
bracket bushings is necessary.
- Remove the brake caliper mounting bolts from the
brake caliper mounting bracket and support the brake
caliper using heavy mechanics wire. Do Not remove the hydraulic brake hose
from the caliper. Refer to
Front Brake Caliper Replacement.
- Remove the disc brake pads (1, 4) from the brake
caliper mounting bracket (3).
- Inspect the disc brake pad mounting hardware for the
following:
- Missing mounting hardware.
- Excessive corrosion.
- Bent pad retainer spring (2).
- Looseness at the brake caliper mounting bracket (3).
- Looseness at the disc brake pads (1, 4).
- Excessive contaminants in the brake caliper mounting bracket (3) surface
and threads.
- If any of the conditions listed are found, the disc brake pad mounting
hardware requires replacement.
- Ensure the disc brake pads are held firmly in place on the brake caliper
mounting bracket, yet slide easily
on the mounting hardware without binding.
