Abstract
A piston assembly is provided for a disc brake assembly to reduce the heat transferred to the hydraulic fluid of the disc brake assembly during braking. The piston assembly preferably includes a piston and a heat insulator designed to be movably coupled to a caliper housing to move a friction member between a release position and a braking position The piston has an internal recess to partially receive the heat insulator. The heat insulator is disposed between the piston and the friction member to reduce heat transfer from the friction member to the piston. Specifically, the piston and the heat insulator are configured to use air spaces to reduce heat transfer from the friction member to the piston.
