A self-adjusting, wear-compensating device for a floating caliper disc brake of the type having a pair of brake pads positioned to engage the disc brake rotor, the device including a rotor and a stator mounted in the caliper housing, the rotary motion of the rotor being converted to linear motion in the stator toward one of the brake pads, a threaded shaft is mounted in a threaded bore in the stator and has one end positioned to engage the brake pad and the other end extending into the rotor, and a one-way clutch is mounted on the other end of the shaft and is operatively connected to the rotor to impart rotary movement to the shaft relative to the stator whenever the rotor rotates more than a predetermined amount to advance the shaft an incremental amount, the clutch is protected from overload damage by a star ring mounted on the shaft in a position to allow the clutch to slip on the shaft.

A self-adjusting wear-compensating device for a floating caliper brake for a brake disc of the type including a caliper housing having brake pads mounted in said housing on the opposite sides of the brake disc, at least one of said pads being movable toward the other of said pads to impose a frictional restraint on the brake disc, said compensating device including a stator mounted in said housing for movement toward and away from said one of said pads, a threaded shaft supported in said stator for movement into engagement with said one of said brake pads, a rotor mounted in said housing for rotary motion relative to said stator, cam means positioned between said rotor and said stator for advancing said stator and said shaft into engagement with said one of said brake pads, a one way roller clutch mounted on said threaded shaft for rotating said shaft relative to said stator as said stator is advanced toward said brake pad by the motion of said rotor and to rotate freely with respect to said shaft when said shaft is moved away from said brake pad, lost motion means operatively connecting said clutch to said rotor to allow said rotor to move a predetermined distance relative to said clutch before said clutch rotates said threaded shaft whereby said shaft will be advanced with respect to said stator an exponential incremental amount each time the rotor is rotated beyond said predetermined distance, and means for frictionally connecting said shaft to said roller clutch to allow said roller clutch to slide with respect to said shaft when the load on the shaft is sufficient to set the brake.
