Disc brake with rotary cam actuated reciprocating pistons

摘要

A disc brake including a pair of cams which contact a pair of cam followers rotatably mounted to pistons slidably carried in apertures provided to one leg of a floating caliper. The cams are secured to a shaft rotatably carried by the caliper. The cams are rotated by the shaft to move the rotary cam followers and pistons in the apertures. The pistons move one brake pad into friction contact with one side of a brake disc. A second brake pad carried by the other leg of the caliper is moved into friction contact with the other side of the disc by the reaction force through the cam shaft and caliper.
