Abstract

In a sliding caliper disc brake actuator, an actuating shaft 39 is rotatable to rotate a helical cam element 23 that in turn axially displaces a non- rotating cam element 22. The elements 22 and 23 are located in a bore 21 in a caliper leg 16 with an automatic adjusting mechanism 18. A helical return spring 58 acts via a washer 59 to bias the cam elements together and a push rod 53 of mechanism 18 is held against rotation by washer 59. A nut 48 of mechanism 18 is threaded onto the rod 53 and engaged by the cam element 22 to transmit axial force to the push rod 53 and relative extension of the push rod from the elements 22, 23 is accomplished by a one-way spring brake 72 acting on the nut 48 and a disc clutch drive 63 to 69 between the cam element 23 and the nut 48. Lost motion is provided at the clutch drive or the spring brake to prevent rotation of the nut 48 on the rod 53 during normal clearance, and rotation of the nut on the push-rod occurs when excessive clearance occurs. <IMAGE>
