BRAKE SERVICE PROCEDURES FOR 2008 Hummer H2 AUTOMOBILES
Disc Brakes -> Delco Dual Piston Sliding Caliper -> Description
Vehicle: 2008 Hummer H2 6.2 V8 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...
