A spot-type automotive disc brake (10) provides parking brake and primary brake functions based on the same pair of friction elements (16, 18) 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 (12) has fixed (42) and actuated (40) friction elements at its opposite sides. A piston (64) and an external bifurcated lever mechanism (72) act completely independently yet symmetrically on the actuated friction element (16) 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.
