In order to minimize instability and significantly reduce braking noise, especially at low speeds, a disc brake's hydraulic piston and piston bore (or other brake actuating element), is angled away from the normal direction perpendicular to the pad backing plate and to the rotor. The brake-applying forces are directed in an inward angled direction, generally toward the rotor and toward the leading edge of the brake pads. Such an arrangement results in reactive forces exceeding or at least equaling the magnitude of force couples caused by the thickness of the brake pads thus causing the pads to exert a greater compressive force on the rotor at the trailing edge of the brake pads than at the leading edge of the brake pads when the vehicle is traveling in a to forward direction. This significantly increases stability when the brakes are applied and minimizes braking noise, especially at low vehicle speeds when such brake noise is typically most significant.
