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.

Block the front wheels before jacking up the rear of

the vehicle.

NOTE: '96 - 98 models shown.

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

slightly, support the rear of the vehicle on safety

stands, then remove the rear wheels.

2. Remove the" brake hose bracket from the trailing arm.

BRAKE HOSE BRACKET

CALIPER BOLT

3.
CALIPER

Remove the caliper bolt, and pivot the caliper up out

of the way. '99 - 01 models only: Hold the caliper pin

with a wrench, being careful not to damage the pin

boot. Remove the caliper bolt with another wrench,

and pivot the caliper up out of the way.

CAUTION:

Thoroughly clean the outside of the caliper to

prevent dust and dirt from entering inside.

Support the caliper with a piece of wire so it

does not hang from the brake hose.

NOTE: Check the hoses and pin boots for damage

and deterioration.

4. Remove the pad shims, pad retainers, and pads.

INNER PAD SHIMS

Check for weakness.

BRAKE PADS

Check for wear.

OUTER PAD SHIM

Check for weakness.
5. Using vernier calipers, measure the thickness of

each brake pad lining.

Brake Pad Thickness:

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

Service Limit: 1.6 mm (0.06 in)

BACKING PLATE

NOTE: Measurement does not include pad backing

plate thickness.

6. If the brake pad thickness is less than the service

limit, replace the rear pads as a set.

7. Clean the caliper thoroughly; remove any rust, and

check for grooves and cracks.

8. Check the brake disc for damage and cracks.

9. Install the pad retainers.
