Abstract
In a drum brake provided with an automatic adjustment device (40c, 40d) effecting the elongation of a spacer interposed between the shoes (12, 14) in the proximity of the brake motor (22), a device (46, 34) makes it possible to neutralize the adjustment device when heavy braking is applied. This device (46, 34) comprises a lever (46, 34) pivoted on one shoe (12, 14) and provided with a projection against which the brake motor bears. A spring (50, 42) normally holds the lever in a position of rest on the shoe supporting it, and the spacer bears against the lever. On heavy braking, the lever pivots, thus neutralizing the adjustment device. The lever can in particular be the hand brake lever (34).
