ABSTRACT:
In a self-energizing disc brake of the spreading type the actuator mechanism incorporates a restrictor in the form of a circumferentially extending discontinuous oil-seal which co-operates with radial faces on the two pressure plates. A secondary, or elevated, reservoir for liquid is therefore defined between said pressure plates by said oil-seal. Liquid can escape from this reservoir in order to enhance the cooling of the braking surfaces, defined by engagement of rotatable friction discs with end faces of a housing, pressure plates and a planar non-rotatable disc. In the brake shown in FIG. 6 two annular members act as seals on the ends of the outermost friction discs.
