<p>A vehicle wheel brake, particularly for a railway vehicle, has an elongate friction pad for engagement with a braking surface. In order to provide for adjustment of the pad without excessive length of the brake, the friction pad is hollow and an elongate adjuster member is located within the friction pad. Relative rotation of the pad and adjuster member, which occurs when there is excessive wear of the friction material, causes axial movement of the friction material to compensate for the wear.</p> |
