<p>A disc brake having a support structure (11) for attachment to a vehicle and a caliper (14) which spans an associated disc (13) and is supported for sliding relative to the disc on the support structure. The caliper includes an actuation piston (15) which is moveable within the caliper in a direction generally parallel to an axis of rotation of the associated disc to move a first brake pad (18a) into contact with a first side of the associated disc and to cause sliding displacement (X) of the calliper relative to the support structure (11) to draw a second brake pad (18b) into contact with the other side of the disc (13). The sliding displacement (X) of the calliper (14) relative to the support structure (11) is guided by the engagement of the piston (15) in a bore (17) formed in the support structure and a ball and ramp mechanism 24 moves the piston (15) relative to the calliper (14).</p> |
