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...

Vehicle: 2005 Chevrolet Express 3500 VAN 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...

Vehicle: 2005 Chevrolet Express 3500 VAN 4.8 V8 GAS
Brake Lines & Linings
Remove one of the front wheels and inspect the brake disc, caliper and linings.
Do not allow any oil or grease on the linings. It is recommended that linings be replaced in sets when worn or damaged.
If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.
Brake Roughness
The most common cause of brake chatter on disc brakes is a variation in thickness of the disc. If roughness or vibration is encountered during highway operation or if pedal pumping is experienced at low speeds, the disc may have excessive thickness v...
