Disc Brake System Description and Operation
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.
