Abstract
A disc brake having a brake shoe wear compensating mechanism in which the sealing gaskets for the operating chamber formed between a pair of spreading members are arranged to be elastically deformable during a brake application, so as to exert a return force during a brake release. A joining element is provided between the spreading members, which utilizes a spring and the friction connection between the joining element and one of the spreading members to exert a return force independently of the return force exerted by the sealing gaskets, to thereby assure a sufficient brake release stroke.
