Anti-Lock Brakes -> Kelsey-Hayes -> Description
Vehicle: 2003 GMC Yukon XL 1500 5.3 V8 FLEX

The ABS cannot, however, increase hydraulic pressure above the amount which is transmitted by the master cylinder during braking.

Vehicle: 2003 GMC Yukon XL 1500 5.3 V8 GAS

In order to properly service power brake systems, a thorough understanding of the various power assist systems is required. These systems provide a mechanical assist, acting to increase the force applied to the master cylinder piston by the driver while decreasing the effort required to obtain acceptable stopping performance. Two basic types of power assist mechanisms are used: vacuum assist diaphragm assemblies which use engine vacuum and in some cases vacuum from an external vacuum pump, and hydraulic assist assemblies which use hydraulic pressure developed by an external pump (us...
