Rear Brake Pads

Inspection and Replacement

• Never use an air hose or dry brush to clean brake

assemblies.

• Use an OSHA-approved vacuum cleaner to avoid

breathing brake dust.

1. Block the front wheels, loosen the rear wheel nuts

slightly, support the rear of vehicle on safety

stands, then remove the rear wheels.

2. Release the parking brake.

3. Remove the two caliper bolts and the caliper from

the bracket.

CAUTION:

• Thoroughly clean the outside of the caliper to pre-

vent dust and dirt from entering inside.

• Support the caliper with a piece of wire so that

it does not hang from the brake hose.

5. Using vernier calipers, measure the thickness of

each brake pad lining.

Standard: 8.5 - 9.5 mm (0.33 - 0.37 in)

Service Limit: 1.6 mm (0.06 in)

BACKING PLATE

11. Install the brake pads and pad shims on the caliper

bracket.

When reusing the pads, always reinstall the brake

pads in their original positions to prevent loss of

braking efficiency.

Contaminated brake discs or pads reduce stop-

ping ability. Keep grease off the discs and pads.

NOTE: Install the inner pad with its wear indicator

facing downward.

12. Rotate the caliper piston clockwise into place in the

cylinder, then align the cutout in the piston with the

tab on the inner pad by turning the piston back.

CAUTION: Lubricate the boot with rubber grease

to avoid twisting the piston boot. If the piston boot

is twisted, back it out so it sits properly.

15. After installation, check for leaks at hose and line

joints and connections, and retighten if necessary.

16. Depress the brake pedal several times to make sure

the brakes work, then test-drive.

NOTE: Engagement of the brake may require a

greater pedal stroke immediately after the brake

pads have been replaced as a set. Several applica-

tions of the brake pedal will restore the normal

pedal stroke.ProCarManuals.com
