Abstract

Improvements to drum brakes comprising brake pads, one of which strangers is resiliently pushed into floating contact with a support block, and the other is driven by a wheel cylinder, having at least one adjusting lever provided with a segment toothed and pivoting on a shoe near the wheel cylinder, the segment cooperating with a ratchet mounted on the same shoe near the support block and an actuating element acting on the adjustment lever with play during braking in order to swing the adjusting lever to absorb the play, characterized by the fact that the ratchet is maintained between the teeth of the segment during brake actuation by mechanical means that cooperate with the support block, and that it is provided with a resilient device, which associated with the actuating element, allows the adjustment lever to remain stationary in relation to a shoe when the mechanical means of There is a predetermined resistance to the pivotal movement of the ratchet.
