ABSTRACT:
The brake comprises two shoes lined with friction elements stressed by a clamping mechanism located between two first ends of the shoes, a fixed anchoring block located between the other two ends of the shoes, and a spacer (44) mounted in the vicinity of the clamping mechanism and bearing by each of its ends on each of the shoes. The spacer comprises a device for automatic lengthening as a function of the wear of the friction elements and consists of a screw
ut system (66-72) controlled by a pawl (84) stressing a toothing (74) fixed to one of the elements (72) of the screw
ut system (66-72), and is characterized in that the pawl (84) is carried by an elastic blade (80) fixed to the spacer (44), the blade (80) being held elastically apart from the spacer (44) via a rocking lever (79) mounted on the spacer, the lever (79) enabling, by rocking, the blade (80) and the spacer (44) to approach one another when the shoes are stressed apart from one another, thus allowing the pawl (84) to rotate the nut (72) and increase the length of the spacer (44).
