Calipers - What you need to know
FLOATING CALIPER DESIGNS
Floating calipers can fail from sticking that can occur from dirt or corrosion if the vehicle is not operated regularly.
  • Causes the pad attached to the caliper to rub on the rotor when the brake is released.
  • Reduces fuel efficiency and cause excessive wear on the affected pad.
  • Additional heat generated can lead to warping of the rotor also.
ALL CALIPERS
All calipers are susceptible to internal breakdown of the rubber seals or phenolic pistons. This cannot visibly be seen and is only detected when leaking occurs.
  • Heat generated in the braking system will eventually break down the rubber seals.
  • Severely worn friction can also cause the piston to overextend and the seal to leak.

Brake Caliper Assembly
The brake caliper is the assembly which houses the brake pads and pistons. The pistons are usually made of aluminum, chrome plated steel, or from a composite material called phenolic. There are two types of calipers: floating or fixed.
