Power Brake Units -> Bendix Brake Booster -> Description
Vehicle: 1998 GMC K3500 Pickup 6.5 V8 DIESEL
In order to properly service power brake systems, a thorough understanding of the power assist system is necessary. These systems provide a mechanical assist, acting to increase the force applied to the master cylinder piston by the driver while decreasing the effort necessary to obtain acceptable stopping performance.
Hydraulic assist units incorporate a basic open center spool valve, hydraulic cylinder and an accumulator assembly in a common housing. When the brake pedal is depressed, the hydraulic piston moves forward closing off fluid relief passages, the spool valve applies flui...

Power Brake Units -> Delco Brake Booster -> Description -> Operation -> Single Diaphragm Type -> Tandem (Dual) Diaphragm Type
Vehicle: 1998 GMC K3500 Pickup 6.5 V8 DIESEL
In order to properly service power brake systems, a thorough understanding of the various power assist systems is necessary. These systems provide a mechanical assist, acting to increase the force applied to the master cylinder piston by the driver while decreasing the effort necessary 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 (...

Hydraulic Brake Systems -> Description -> Hydraulic Control Valves -> Master Cylinder
Vehicle: 1998 GMC K3500 Pickup 5.7 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...
