<p>A brake caliper (12) includes a housing having at least one bore formed therein. A coolant passage (22) is formed through the housing and extends radially outwardly from the bore and is fluidically coupled thereto. The coolant passage (22) can accept a coolant, which can be actively moved or it can be passively moved. The brake caliper (12) also has at least one piston (16) slidably mounted in the bore. The piston can be made from a thermally conductive material. The piston (16) can include a wall that is thicker at a first end there of than at the second end thereof . The thicker end is that which contacts a brake pad. A method of cooling a disc brake assembly is also provided. The coolant passage takes heat out of the disc brake assembly before it reaches the brake fluid. Heat is dissipated by thermal exchange into the caliper, coolant, and/or the atmosphere.</p> |
