Abstract

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.
