Power Brake Units -> Delco Brake Booster -> General Service
Vehicle: 2002 Chevrolet Avalanche 1500 5.3 V8 GAS
Certain general service procedures apply, regardless of whether the brakes are vacuum or hydraulically assisted. Only top quality, clean brake fluid should be used. More seals and valves are used with power brake systems than with ordinary brakes, so an inferior brake fluid will do much more damage. For the same reason, ensure all dirt is kept out of the system. Additionally, on models with hydraulic assist brakes, care must be taken not to mix the fluids of the booster hydraulic system and brake hydraulic system as the fluids are not compatible.
If the power unit fails, the brak...

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...

Brake Lines & Linings
Remove one of the front wheels and inspect the brake disc, caliper and linings.
Do not allow any oil or grease on the linings. It is recommended that linings be replaced in sets when worn or damaged.
If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.
Brake Roughness
The most common cause of brake chatter on disc brakes is a variation in thickness of the disc. If roughness or vibration is encountered during highway operation or if pedal pumping is experienced at low speeds, the disc may have excessive thickness v...

Drum Brakes -> Precautions
Vehicle: 2002 Chevrolet Avalanche 1500 5.3 V8 GAS
When working on or around brake assemblies, care must be taken to prevent breathing asbestos dust, as many manufacturers incorporate asbestos fibers in the production of brake linings. During routine service operations, the amount of asbestos dust from brake lining wear is at a low level because of a chemical breakdown during use and a few precautions will minimize exposure.. Do not sand or grind brake linings unless suitable local exhaust ventilation equipment is used to prevent excessiv...
