Abstract: A recentering device for a drum brake is provided in an opening of the strut placed between the shoes and includes a spring placed between two cups which are capable of sliding in the opening and both engage a fixed bearing element on the brake support plate and are supported by one of the shoulders formed in the opening. During braking, the strut compresses the spring through one of the two cups by way of the corresponding shoulders. On termination of braking, the spring recenters the strut, driving it back until one of the cups regains its bearing on the associated fixed bearing element, thus recentering the shoes bearing on the strut.

Abstract: The invention relates to a drum brake in which the strut (32, 132, 232) is maintained at an approximately constant distance relative to the brake motor (20, 120, 220). The brake comprises a strut (32, 132, 232) disposed between two brake shoes (12, 112, 212; 14, 114, 214) and maintaining the brake shoes in spaced-apart relationship through a wear compensating device (38, 137, 138, 237, 238). The strut includes an inclined plane (60, 160, 260) cooperating, in proportion to wear of the friction elements (16, 116, 216; 18, 118, 218), with a projection (64, 164, 264) carried by one shoe, the inclined plane approximating an arc of a circle centered on the center of rotation of the associated shoe during wear of the associated friction elements. The invention may be applied to brakes for automotive vehicles.
