<p>In a spreading disc brake, actuating movement of an actautor assembly (9) in a stationary housing (1) can be effected hydraulically by a piston (33) working in a cylinder (31) and acting on a pull-rod (20) through a rocking thrust coupling (39, 43), and the pull-rod (20) is adapted for connection to a hand-lever in order to apply the brake manually or mechanically. The thrust coupling (39, 43) is provided at an intermediate point in the length of a lever (41), a first pivotal connection (44) is provided between the pull-rod (20) and an intermediate point in the length of the lever (41), a second pivotal connection (45) is provided between one end of the lever (41) and the housing (1), and a third pivotal connection (46) is provided between the opposite end of the lever (41) and a transmission member (52) for connection to the hand-lever.</p> |
