BRAKE SERVICE PROCEDURES FOR 2002 Chevrolet Avalanche 2500 AUTOMOBILES
Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 2002 Chevrolet Avalanche 2500 cars and light trucks from 1990+.
Anti-Lock Brakes -> Kelsey-Hayes -> Description
Vehicle: 2002 Chevrolet Avalanche 2500 8.1 V8 GAS
When wheel slip is detected during a brake application, the ABS enters anti-lock mode. During anti-lock braking, hydraulic pressure in the individual wheel circuits is controlled to prevent any wheel from slipping. A separate hydraulic line and specific solenoid valves are provided for each wheel. The ABS can decrease, hold, or increase hydraulic pressure to each wheel brake. The ABS cannot, however, increase hydraulic pressure above the amount which is transmitted by the master cylinder during braking.
During anti-lock braking, a series of rapid pulsations is felt in the brake pedal...

Brake System Bleed
Gravity and vacuum bleeding procedures are not recommended for use with the anti-lock brake system. The manual bleed procedure is the preferred method, although pressure bleeding is also possible. Do not pump the brake pedal during the bleeding process, as fluid aeration may occur.
Manual Bleed
- Raise and support vehicle, then connect a clear plastic tube to brake bleed screw at righthand rear wheel.
- Place free end of tube in a glass jar partially filled with clean brake fluid. Ensure end of tube remains submerged in fluid and master cylinder reservoir is kept full.

Disc Brakes -> Delco Dual Piston Sliding Caliper -> Description
Vehicle: 2002 Chevrolet Avalanche 2500 8.1 V8 GAS
The caliper mounts in a way that allows the caliper to move laterally inboard as the brake pads wear. The caliper housing is a one piece casting with the inboard side containing the piston bore. The piston seal also acts as a return mechanism for the piston.
Applying the brake pedal causes the hydraulic pressure that moves the caliper piston. The piston then forces the inboard brake pad against the inboard braking surface of the rotor. Increasing the force against...

Vehicle: 2002 Chevrolet Avalanche 2500 8.1 V8 GAS
General System
- Inspect components for damage or unusual wear. Replace as required.
- Inspect backing plate mounting bolts and ensure they are tight.
- Inspect wheel cylinders. Excessive fluid indicates cup leakage and need for wheel cylinder replacement. Slight amount of fluid is always present and is considered normal, acting as lubricant for cylinder pistons.
- Inspect adjuster screw operation. If satisfactory, lightly lubricate adjusting screw and washer with suitable brake lube. If operation is unsatisfactory, replace.
- Clean rust and dirt from shoe contact surfaces on backing plate using fi...
