Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 2007 Chevrolet Express 2500 cars and light trucks from 1990+.
Anti-Lock Brakes -> Kelsey-Hayes -> Description
Vehicle: 2007 Chevrolet Express 2500 6.6 V8 DIESEL
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...

Hydraulic Brake Systems -> Description -> Hydraulic Control Valves -> Master Cylinder
Vehicle: 2007 Chevrolet Express 2500 4.8 V8 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...
