A pad assembly includes a carrier plate, a backing plate to one side of which is secured at least one friction pad and which is mounted on its alternate side on the carrier plate, a spring acting between the carrier plate and the backing plate and allowing for limited rocking and/or linear movement of the backing plate relative to the carrier plate against the action of the spring. A plurality of transmitting members are secured to one or the other of the carrier plate or the backing plate and project to engage the other so as to enable the transmission of force between the two plates. The arrangement of the force transmitting members is such that at least two of the force transmitting members are generally equiangularly arranged about the geometric center of the carrier plate.
