Brake Rotor/Disc: Description and Operation
Front Disc Brake
Description and Operation
The brake disc is mounted on the wheel studs and is clamped between the wheel and hub. Cooling ducts run through the center of the brake disc to
provide the required ventilation to keep the disc cool under operating conditions.
The caliper carrier, which is secured to the hub carrier by two bolts, carries the single-piston caliper housing. The caliper housing is secured to the
caliper carrier by two guide-pins and an anti-rattle spring. When the brakes are applied the caliper-housing piston pushes the brake pad in front of it,
towards the brake disc. This movement forces the caliper housing to move along the guide-pins, in the opposite direction of the piston, to apply the
second brake pad. The brake disc is therefore gripped between the two pads. As brake pressure is increased the grip on the brake disc is increased to
slow-down the rotation of the road wheel.
The disc brakes require no adjustment.
