Abstract
The invention concerns a drum brake of the type comprising brake actuator inserted between two adjacent ends of two brake shoes, the opposite ends thereof cooperating with a fixed anchoring member. An adjusting lever is pivotable relative to one of the shoes upon wear of the linings carried by the shoes, to control relative rotation between two elements of an extensible member. According to the invention, a resilient means normally connect the extensible member to the one shoe and an adjustment limitor are provided to connect the extensible member to the lever when the relative motion between the free end of the lever and the one shoe exceeds a predetermined value.
