BRAKE SERVICE PROCEDURES FOR 2007 Hummer H3 AUTOMOBILES
Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 2007 Hummer H3 cars and light trucks from 1990+.
Power Brake Units -> Delco Brake Booster -> Description -> Operation -> Single Diaphragm Type -> Tandem (Dual) Diaphragm Type
Vehicle: 2007 Hummer H3 X 3.7 L5 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...

Disc Brakes -> Delco Dual Piston Sliding Caliper -> Description
Vehicle: 2007 Hummer H3 3.7 L5 GAS
The caliper mounts in a way that allows the caliper to move laterally inboard as the brake pads wear. The caliper housing is a one piece casting with the inboard side containing the piston bore. The piston seal also acts as a return mechanism for the piston.
Applying the brake pedal causes the hydraulic pressure that moves the caliper piston. The piston then forces the inboard brake pad against the inboard braking surface of the rotor. Increasing the force against...
