Abstract
A spring member is biased toward the outer peripheral edge of a vented disk and is held out of engagement therewith by a locking device. As the brake pads wear, the pad backing plates come closer together, thus compressing the locking device and releasing the spring so that it may engage the ribs in the outer periphery of the disk. The spring member is shaped to prevent excessive protrusion into the apertures in the disk and to permit reverse rotation of the disk.
