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.

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.

Piston end and inner shim B contact surface

Inner shim A contact surface (both sides)

Pads and caliper bracket contact surface

Outer pad and caliper body contact surface

Outer pad shim and outer pad contact surface

grease evenly to the designated points.

PISTON

Apply Molykote M77

to both sides of shims.

INNER SHIM B

INNER SHIM A

WEAR INDICATOR

Install inner pad with its

wear indicator downward.

BRAKE PADS

OUTER PAD SHIM

Apply Molykote M77

to both sides of shim.

11. Install the brake pads and pad shims correctly.

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 pad with the wear indicator on

the inside.
12. Push in the piston so that the caliper will fit over the

pads. Make sure the piston boot is in position to

prevent damaging it when pivoting the caliper

down.

13.
Pivot the caliper down into position, then install the

caliper bolt and tighten it. '99 - 01 models only: Hold

the caliper pin with a wrench, being careful not to

damage the pin boot. Install the caliper bolt with

another wrench, and torque the caliper bolt to the

proper specification.

CAUTION: Be careful not damage the pin boot

when pivoting the caliper down.

14. Install the brake hose bracket on the trailing arm.

NOTE: Inspect the brake hose for interference and

twisting.

15. Press 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.

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

joints or connections, and retighten if necessary.ProCarManuals.com
