BRAKE SERVICE PROCEDURES FOR 2002 GMC Yukon AUTOMOBILES
Anti-Lock Brakes -> Kelsey-Hayes -> Description
Vehicle: 2002 GMC Yukon 5.3 V8 FLEX
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...
