The rear disc brake assembly consists of the following major components:
•Caliper
• Caliper adapter bracket
• Brake pads
• Rotor
• Parking brake shoes
CAUTION:
•Use DOT 4 brake fluid or equivalent from a tightly sealed container. Do not use petroleum-based
fluids, which will cause seal damage in the brake system.
• Brake fluid will damage painted surfaces. If brake fluid is spilled on any painted surfaces, wash
it off immediately with water.
• Never use gasoline, kerosene, alcohol, motor oil, transmission fluid, or any fluid containing min-
eral oil to clean system components. These fluids damage rubber cups and seals.
• During service procedures, grease or any other foreign material must be kept off the caliper
assembly, brake pads, brake rotor and external surfaces of the hub.
• When handling the brake rotor and caliper, be careful to avoid damaging the brake rotor and
caliper, and scratching or nicking the brake shoe lining.
Operation
Applying the brake pedal uses lever action to push a rod into the brake booster, which through the use of vacuum,
boosts the force of the rod and then transmits this force into the master cylinder. This produces hydraulic pressure in
the master cylinder. On vehicles not equipped with ABS, the hydraulic pressure is transmitted by brake fluid through
the brake tubes to the individual brake calipers or wheel cylinders. On vehicles equipped with ABS, the hydraulic
pressure is transmitted by brake fluid through the brake tubes to the ABS hydraulic control unit (HCU), which then
distributes that pressure to the individual brake calipers and wheel cylinders. The brake calipers use hydraulic pres-
sure to apply the brake pads. The application of the brake pads or shoes will cause the rotation of the wheels to slow
or stop depending on how much brake pressure is applied. The parking brakes carry out the same function except
that they are mechanically actuated by a cable that connects only to the rear brakes.

Diagnostic Help
Brake diagnosis involves determining if the concern is related to a mechanical, hydraulic, electrical or vacuum oper-
ated component.
NOTE :
The brake reservoir fluid level will decrease in proportion to normal lining wear.
NOTE :
Brake fluid tends to darken over time. This is normal and should not be mistaken for contamination.
Preliminary Brake Check:
•Check the condition of the tires and wheels. Damaged wheels and worn, damaged or under inflated tires can
cause a pull, shudder, vibration and a condition similar to brake grab.
• If a complaint was based on noise while braking, check the suspension components. Jounce the front and the
rear of vehicle and listen for anything that might be caused by a loose, worn or damaged suspension or steer-
ing component.
• Inspect the brake fluid level and condition.
1. If the fluid level is abnormally low, look for any evidence of leaks at the calipers, brake lines, master cyl-
inder and at the Antilock Brake System (ABS) Hydraulic Control Unit (HCU).
2. If the fluid appears to be contaminated, drain a sample to examine.
• The system will have to be flushed if the fluid is separated into layers, or contains a substance other than
brake fluid. The system seals, cups, hoses, master cylinder and HCU will also have to be replaced after flush-
ing. Use clean brake fluid to flush the system.
• Check the parking brake operation. Verify free movement and full release of the cables and the lever. Also note
if the vehicle was being operated with the parking brake partially applied.
• Check the brake pedal operation. Verify that the pedal does not bind and has adequate free play. If the pedal
lacks free play, check the pedal and the power booster for looseness or for a binding condition. DO NOT road
test the vehicle until the condition is located and corrected.
• Check the vacuum booster check valve and vacuum supply hose.
• If the preliminary checks appear to be OK, road test the vehicle.
Brake Noise
CONDITION POSSIBLE CAUSES CORRECTION
Disc Brake Chirp · Excessive brake rotor runout.
· Small particles· Diagnose and correct as
necessary.
Disc Brake Rattle Or Clunk · Broken or missing spring clips.
· Caliper guide pin bolts loose.
· Missing abutment shims.
· Small metal particles· Replace brake pads.
· Tighten guide pin bolts.
· Replace missing abutment shims.
Disc Brake Squeak At Low Speed
(While Applying Light Brake Pedal
Effort) · Brake shoe linings.
· Replace brake pads.
Scraping Or Whirring · ABS wheel speed sensor hitting
tone wheel.· Inspect, correct or replace faulty
component(s).
