ABSTRACT:
A disk brake assembly includes a rotary brake disk rotatable with a wheel and a mounting member fixed to a stationary member of a vehicle. A guide member is fixed at one end portion to the mounting member. A caliper member having a tubular portion slidably supported on the guide member is movable in an axial direction with the caliper member straddling a portion of the brake disk and having a fluid actuator provided with a piston on one side thereof to press an inner brake pad against one face of the brake disk and a reaction portion on the opposite side thereof to press an outer brake pad against the other face of the brake disk. The outer brake pad has a projection portion projected outwardly of the brake disk at the center of its backing plate and a spring member is disposed between the outer brake pad and the reaction portion and rigidly supported the outer brake pad on the caliper member. The spring member urges the outer brake pad outwardly of the brake disk and has a center clipping portion rigidly and elastically clipped to the projection portion. A pair of arm portions extend from both ends of the center clipping portion and engage with the reaction portion so as to decrease the diameter of the center clipping portion. A rising portion of the spring elastically engages with an outer surface of the reaction portion at the end of the arm portions.
