A brake caliper has a removable bridge that acts as a rigid mount for a pair of brake pad holders. The removable bridge is retained on the caliper body by spring loaded push button that allows quick removal for replacement of the brake pads, which is especially suited for automotive racing situations. The bridge is snapped in place and rigidly retained on caliper body when in use.

Quick release removable bridge caliper

A brake caliper has a piston retained in a bore that abuts a brake pad for moving the brake pad into selective engagement with a rotor to effect braking. The piston has a composite cap that is formed of a cap piece made of strong material, such as steel, and an insulator, made of polyimide resin material, for example. The insulator is preferably in the form of a ring clamped between the cap piece and the piston to create a thermal break and minimize heat transfer from the brake pad to the piston and caliper assembly.
