Abstract
A brake mechanism fixed to a member allowing limited reciprocal motion and providing a restorative force to the movable member in one direction of movement thereof. A brake mechanism includes a rotor fixed to and wheel about an axle axis has a caliper assembly spanning the rotor with inboard and outboard friction members supported on either side of the rotor for selectively engaging the rotor and braking the wheel. A piston is fixed to the caliper of the inboard friction member for moving the inboard friction member toward the rotor and including a piston seal which, upon removal of fluidic pressure from the cylinder, resiliently urges the inboard friction member away from the rotor. A bracket is fixed to the vehicle supports the caliper on a pair of generally cylindrical guide pins fixed to one of the anchor bracket and caliper assembly and is movable within a pair of generally cylindrical guide pin bores of the anchor bracket and caliper assembly. A pair of central cylindrical shells and an end engaging a pin shoulder to provide the restorative force and a radially outer portion of reduced rigidity such as a plurality of fins frictionally engaging the aperture.
