Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 2002 Chevrolet Trailblazer cars and light trucks from 1990+.
Hydraulic Brake Systems -> Description -> Hydraulic Control Valves -> Master Cylinder
Vehicle: 2002 Chevrolet Trailblazer 4.2 L6 GAS
Master Cylinder
Some vehicles use a conventional tandem master cylinder with two hydraulic pistons operating in-line. The primary piston controls the front brake system and the secondary piston controls the rear brake system.
Other models use a master cylinder that operates the same as the conventional master cylinder, but also incorporates a quick take-up feature in the rear chamber to reduce excessive pedal travel which may result from increased fluid displacement required to move the low drag caliper piston out against the rotor.
The quick take-up uses a spring-loaded ball check val...

Brake System Bleed

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.

Anti-Lock Brakes -> Kelsey-Hayes -> Description
Vehicle: 2002 Chevrolet Trailblazer 4.2 L6 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...
