More Information
Summary:The friction pad assembly of the present invention has a generally rectangular back plate with two retaining tabs projecting from opposite side edge regions, at an angle to the general plane of the back plate. The support or shoe is also generally rectangular and has a recess formed in each of two opposing side edges, the retaining tabs on the back plate engaging snugly into these recesses. The support has a further H-shaped recess in its front face within which an elongate spring plate is secured so as to project beyond opposing ends of said support. Thus, in use, the friction pad assembly can be quickly and simply mounted on the support and when the brake is operated the end region of the spring plate through which pad drag is passed to pad guides, flexes to thus allow for unhindered axial movement of the friction pad assembly and support.
