Cooling for brake disc - has surface layer removed on rear of disc and replaced with heat conducting layer

The brake disc is processed to remove the surface skin from the casting process, in areas not touched by the disc pads. The surfaces are treated to increase the heat transfer to the cooling airstream and can be fitted with heat fins. The surface layer is removed with a coarse turning tool, leaving a grooved surface, with increased surface area. Another method uses chemical etching or abrasive jet etching. ADVANTAGE - Improved cooling effect, suitable for passenger service vehicles, e.g. frequent stopping.

An electrically operated, mechanically tensioned, fully coated disc brake for cars has a revolving two-part brake housing (5,6), ribbed on the outside and two brake discs inside (10,11) equipped with friction coats (8,9). The discs are located so as to be freely movable axially on a brake carrier (12) connected to the axle, relative to the smooth inner surface of the housing. The discs on their inner surfaces opposite the friction surfaces possess rising recesses in which balls (17,18) or rollers (22,23) lie.
