Abstract:
A disc brake comprising a disc, a rotatable hub supporting said disc for axial sliding movement thereon, friction material pads arranged on opposite sides of said disc, each pad having a friction surface facing one of said opposite sides, an operating mechanism operable to move a first of the pads into frictional contact with a first surface of the disc and to move the disc on the hub to bring a second surface of the disc into frictional contact with a second of said pads so that both pads apply a braking force thereto, the operating mechanism comprising a support body located on one side of the disc;a cylinder fixedly mounted on the support body and a piston in the cylinder, the piston being movable when fluid under pressure is introduced into the cylinder to urge a first of said pads towards the disc, a guidance member suspended from the support body, said guidance member projecting from the support body and having an end surface beyond the outer edge of the disc, the first of said pads being suspended from said guidance member for sliding movement thereon, an abutment member fixedly attached to the end surface of said guidance member, said second of said friction material pads being fixedly supported on said abutment member with the friction surface of the pad facing said second surface; anda plurality of bores extending through said guidance member, each said bore having continuing aligned portions in said support body and said abutment and a plurality of elongated tensile bolts for absorbing the bending and shearing forces imposed on said guidance member, each said bolt extending within one of said plurality of bores, including said continuing aligned portions and fixedly interconnecting said support body, said guidance member and said abutment.
