摘要： An electrically operated drum brake (10) has a brake shoe (11, 12) displaceable into contact with an associated rotatable brake drum by an electrical actuator (14) in the form of a screwing jack to apply the brake. The shoe reacts against a support abutment (13a) carrying a load sensing means (40) which actions discontinuance of operation of the electrical actuator in a brake disengaging sense when the load applied to the support abutment by the shoe falls to a predetermined level.

摘要： In a clearance compensator a rod (12) is fixed to one of the shoes of the brake and is slidable in an intermediate element (13) threadedly engaged in another rod (11) secured to the other shoe. A heat-sensitive bi-metal strip (18) projects from a leaf spring (14) operable to urge the rod (12) away from the intermediate element (13). The bi-metal strip (18) is orientated substantially tangentially of a ratchet wheel (17) fixed to the intermediate element (13); at its free end, the bi-metal strip (18) has a stop element (18a) for engaging the ratchet wheel (17). At temperatures above a predetermined value, the strip (18) assumes a heat-induced deflected condition in which the stop element (18a) is disengaged from the wheel (17).
