Abstract:
A disc brake, comprising:a rotatable disc having an axis, an outer periphery, and first and second sides;a first friction member on said first side;a second friction member on said second side;a mounting member adapted to be secured to a non-rotating part of a vehicle;a caliper including(i) a caliper body having a cylinder portion disposed on said first side and provided with a cylinder bore, a claw portion disposed on said second side, and a bridge portion extending over said outer periphery of said disc and interconnecting said cylinder portion to said claw portion; and(ii) first and second mounting portions each having a proximal end provided substantially adjacent said cylinder portion and a distal end spaced from said caliper body, wherein said first and second mounting portions extend oppositely from said caliper body with respect to an axial plane of said disc from said proximal ends to said distal ends, respectively, such that sections including said proximal and distal ends of each of said first and second mounting portions, respectively, lie outside of said outer periphery of said disc;first and second sliding pins provided on one of said mounting member and said first and second mounting portions, respectively;first and second guide holes provided in the other of said mounting member and said first and second mounting portions, respectively, wherein said sliding pins are receivable within said guide holes, respectively, such that said caliper is slidably supportable by said mounting member; anda piston provided in said cylinder portion, wherein said piston is operable to press said first friction member against said first side of said disc, whereby said caliper slides relative to said mounting member via said sliding pins and guide holes such that said claw portion presses said second friction member against said second side of said disc,wherein each of said first and second mounting portions has opposite side surfaces facing to and away from said disc, respectively, with each of said first and second mounting portions being disposed such that both said opposite side surfaces of said proximal ends, respectively, are respectively axially closer to said disc than are both said opposite side surfaces of said distal ends, respectively.
