BRAKE SERVICE PROCEDURES FOR 2006 GMC Sierra 2500 HD AUTOMOBILES

Anti-Lock Brakes -> Kelsey-Hayes -> Description
Vehicle: 2006 GMC Sierra 2500 HD WT 6.0 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...

Do not smoke or allow an open flame of any type when working on or near any fuel system related components. The highly flammable vapor mixtures may ignite, resulting in serious personal injury.

Prior to disconnecting fuel lines, the fuel system pressure must be relieved to prevent accidental spray of fuel.

After the battery has been disconnected and reconnected, some abnormal driveability symptoms may occur. The vehicle may need to be driven while the vehicle relearns its adaptive strategy.
