摘要

A self-energizing disc brake of the spreading type is provided with an actuator unit incorporating an hydraulically-operable mechanism and a mechanically-operable mechanism. The unit comprises a member which is detachably secured to the housing of the brake and provides a mounting for both mechanisms which extend into the housing through a common opening. The hydraulically-operable mechanism comprises a cylinder in which work opposed pistons acting to separate lugs on the pressure plates and the mechanically-operable mechanism may take any convenient form. The cylinder is tangentially arranged with respect to the plates.
