Abstract
For the pneumatic actuation of a multi-disc brake, plungers which are distributed circumferentially around the thrust ring (not shown) of the disc pack are paired and each pair is driven in the brake-application direction by a common pneumatic actuator. Thrust is transmitted from each actuator to the associated pair of plungers by a respective pair of transmission elements each of which moves at right angles to the associated actuator and plungers, each element having at its opposite ends ball-and-ramp formations with taper angles of less than 45.degree. such that the travel of each element is less than that of the associated actuator and the travel of each plunger is less than that of the associated element but the force applied by each actuator to the associated pair of plungers has twice been multiplied.
