Disc brake caliper with auxiliary system to cool brake fluid

A disc brake caliper for use in an automobile having a rotor which is simultaneously rotated with a wheel hub, the caliper comprising:

• (a) a housing defined by an outside boundary and wherein the housing has an opening which includes a first inwardly facing surface and a second inwardly facing surface, and wherein the housing is secured on the automobile such that the rotor is positioned in the opening, and the first inwardly facing surface and the second inwardly facing surface axially oppose each other relative to the rotation of the rotor, and wherein the housing further has a first bore located on the first inwardly facing surface and a second bore located on the second inwardly facing surface, each of the bores being adapted to receive a piston which may be activated simultaneous with the piston in the other bore to press a friction pad against the rotor and thereby clamp the rotor therebetween to provide a braking action against the rotor;
• (b) a first conduit for conveying an actuating fluid to the first and the second bores, and wherein the pistons are activated upon flow of the actuating fluid directed through the first conduit;
• and
• (c) a second conduit which conveys a coolant through the housing to a region proximal the first conduit, and wherein heat is conducted away from the actuating fluid upon flow of the coolant directed through the second conduit, and wherein the second conduit includes a groove formed in the outside boundary of the housing and a plate which fits over the groove.
