<p>PROBLEM TO BE SOLVED: To eliminate nonconformity due to extension and contraction of a back plate by reducing work to prostrate a piston due to thermal expansion of the back plate to the utmost, preventing galling by the piston and liquid spill from a corner seal and preventing collisional hammering sound of a cantilever pin and a cutout groove. SOLUTION: A lining 2 is supported by engaging a cantilever pin 5 fixed to a torque receiving part 1 and by providing U shaped cutout grooves 3a at two points on an outer periphery and an inner periphery at a roughly central position of a back plate of the lining 2 against the radial direction of a disc rotor in a caliper brake of a type to generate braking force to the disc rotor through a pair of the linings 2 by hydraulic pressure to be supplied to a hydraulic cylinder part 1b by arranging a pair of the linings 2 on both ends of the disc rotor and providing the hydraulic cylinder part 1b on a caliper straddling on this disc rotor.</p> |
