CA 2116577
A disc brake assembly (1) has a pair of pivoted brake arms (4) carrying brake pads (3) located on re- spective opposite sides of a disc (2). The brake arms (4) are biased towards each other by springs to clamp the brake pads (3) against the disc (2). The disc brake assembly (1) also includes a cam member (9) having two double-sided cams, each of which co-acts with a cam follower (12) mounted on a respective brake arm (4). The cam member (9) is connected to an actuating cylinder (6). When the cylinder (6) is energised, the inner cam surfaces drive the cam followers (12) apart to release the brake. When the cylinder (6) is not ener- gised, the outer cam surfaces prevent outward move- ment of the cam followers (12) thereby positively locking the brake pads (3) against the disc (2). The disc brake also includes a mechanism for automati- cally adjusting the position of the brake pads (3) to compensate for wear.
