ABSTRACT:
A disc brake includes a pair of friction elements which are movable by a hydraulic actuator and a caliper into engagement with the disc to effectuate braking. A torque member movably supports the caliper. The hydraulic actuator includes a piston cup and an anti-rattle spring is disposed within the piston cup and releasably engaged with one of the pair of friction elements to eliminate noise generated between the one friction element and the caliper, the torque member, or the piston cup. In particular, the anti-rattle spring comprises a split ring having a polygonal circumference. The split ring is contracted radially for insertion into the piston cup and sides of the polygonal surface are expanded radially to receive the one friction element. A pair of tabs on the split ring releasably engages the one friction element to retain the same in engagement with the piston cup.
