Abstract
A rail vehicle brake actuator is provided with leaf spring hangers (4, 5) to laterally move to follow axial movement of wheels during braking. The hangers are rotatably attached to both a brake block holder and a shaft 7 on an actuator bracket (2). Rotary braking movement is provided by pivot joints having rubber O-rings and washers held together under prestress. The leaf spring hangers pivot laterally to follow axial wheel movement.
