ABSTRACT:
The device comprises a hydraulic operating actuator (5), associated with a friction element (4) and capable of being operated by a liquid under pressure to bring the friction element into frictional contact with the component to be braked (2); and a pneumatic actuator means (10), incorporating a hydraulic chamber (20), joined to the hydraulic actuator (5), and a pneumatic chamber (14) capable of being joined to a source of gas under pressure, the two chambers being separated by a movable wall structure forming a piston, the hydraulic chamber (20) being at least partially defined by a flexible elastic envelope (21) arranged in the immediate vicinity of the hydraulic operating actuator.
