Pin guided push-pull caliper

摘要

A disc brake for a motor vehicle includes a rotor mounted to a wheel and rotatable about a first axis therewith; a pair of parallel-spaced pins removably mounted to the vehicle chassis so as to extend in a direction generally parallel to the first axis; a pair of brake shoes having slots for receiving the pins on either side of the rotor so as to place brake linings respectively mounted on the pins in opposition with complementary annular friction surfaces on either side of the rotor; and a caliper slidably supported by the two pins so as to straddle the rotor and both brake shoes, respectively. The slots of the brake shoes are defined in part by a finger configured to deflect responsive to a brake load and the deflection of the finger enables the sequential engagement of the brake shoes against the pins.
