Abstract

The fail-safe device is made of a stack of Belville washers or similar dish springs which are normally held in compressed state by an auxiliary hydraulic actuator which may be arranged together with the stack in one of the legs of the brake saddle, the main hydraulic actuator of the brake being embodied in the other leg. An automatic brake clearance take-up device is arranged for the clearance to remain within the limits of the deflection of the spring stack. The take-up device has a manually operable element for releasing the brake against the action of the fail-safe device.
