A disc brake which comprises a torque absorbing member associated with operating means capable of urging at least one friction member onto a brake disc. The friction member cooperates with the circumferentially spaced edges of an aperture formed in the torque absorbing member by way of one guide key. The key comprises at least one recess permitting radial extraction of the friction member through the aperture when the friction member is situated opposite the recess. The key is capable of occupying an operative position, in which the recess is offset relative to the friction member, and a removal position in which the recess is opposite the friction member. The cross-section of the key forms a V of which the inside face cooperates with the corresponding edge of the aperture and the outside faces slidably receive the friction member. One arm of the V defined by the key extends towards the brake interior whereas the other arm is substantially perpendicular to the radial plane of symmetry of the brake. The recess is formed in the arm which extends towards the brake interior. |
