Disc Brake System Description and Operation for Chevrolet Chevy Suburban - 4WD 2008
System Component Description
The disc brake system consists of the following components:
Disc Brake Pads: Applies mechanical output force from the hydraulic
brake calipers to friction surfaces of brake rotors.
Disc Brake Rotors: Uses mechanical output force applied to friction
surfaces from the disc brake pads to slow speed of tire and wheel assembly rotation.
Disc Brake Pad Hardware: Secures disc brake pads firmly in proper
relationship to the hydraulic brake calipers. Enables a sliding motion of brake pads
when mechanical output force is applied.
Disc Brake Caliper Hardware: Provides mounting for hydraulic
brake caliper and secures the caliper firmly in proper relationship to caliper bracket.
Enables a sliding motion of the brake caliper to the brake pads when mechanical
output force is applied.
System Operation
Mechanical output force is applied from the hydraulic brake caliper pistons
to the inner brake pads. As the pistons press the inner brake pads outward, the
caliper housings draw the outer brake pads inward. This allows the output force
to be equally distributed. The brake pads apply the output force to the friction
surfaces on both sides of the brake rotors, which slows the rotation of the tire
and wheel assemblies. The correct function of both the brake pad and brake caliper
hardware is essential for even distribution of braking force.
