ABSTRACT:
The actuating device comprises an actuating nut and spindle combination disposed in a brake piston, the spindle being rotated by an actuating lever and the nut having an outer thread engaging an inner thread of the brake piston thereby providing a brake pad clearance adjusting device. The brake piston is rotatably connected to the spindle via a one-way clutch for progressively screwing the brake piston out of the nut to compensate for brake pad wear. The one-way clutch is connected to the spindle by a rod extending through an axial bore in the spindle enabling the clutch to be unlocked from the outside of the actuating device for resetting the brake piston when worn brake shoes are being replaced.
