Abstract
A spot-type automotive disc brake ( ) provides parking brake and primary brake functions based on the same pair of friction elements ( ) and without resorting to supplemental drums or supplemental friction elements. The mechanism is simple and can be made at a size applicable to small mass produced vehicles. A sliding disc ( ) has fixed ( ) and actuated ( ) friction elements at its opposite sides. A piston ( ) and an external bifurcated lever mechanism ( ) act completely independently yet symmetrically on the actuated friction element ( ) without any common thrust-transmitting parts, whereby the asymmetry and complexity and consequential unreliability and high cost and duplication of mechanisms of prior proposals is avoided.
