摘要：<p>The invention relates to a disk parking brake comprising a piston for applying brake shoes to the disk, means for supplying a fluid which is sufficiently pressurised to be able to firmly apply the brake shoes to the disk as required, and means for blocking the piston in a first state wherein the brake shoes are firmly applied to the disk, said blocking means comprising a key and an actuator for displacing said key, as required, between a first position wherein the brake piston can withdraw and a second position wherein the key blocks the withdrawal of the piston. Said brake comprises a wear take-up device for the brake shoes which ensures the transmission of force between the key and the piston when the parking brake is activated, and comprises a screw and a bolt which unscrew in relation to each other as the brake shoes wear, the screw having a surface pressing against the key and the bolt having a surface pressing against the piston.</p>
