sensor is typically positioned to detect the amount of force applied by the inner break pad to the rotor disc this load sensor is operatively coupled to a mechanism for controlling the position of the caliper housing and in turn the force applied by the outer break pad to equalize or u201c center u201d the force applied by the two brake pads on the rotor disc such caliper assembly includes at least a brake caliper that comprises a caliper housing having a rotor channel adapted to receive a rotor such as a rotor disc therein where the rotor channel has a first axial surface adapted to seat an outer brake pad thereon the brake caliper also includes a piston assembly mounted to the housing on an axial side of the rotor channel opposite that of the outer brake pad the piston assembly includes a piston nut reciprocatable towards and away from the rotor channel where the piston nut is adapted to seat an inner brake pad thereon a driven screw threaded into the piston nut which axially drives the piston nut towards or away from the rotor disc in the rotor channel as illustrated in fig1 4 the brake caliper assembly 10 of the present invention which is applicable for use in either an electric or hydraulic braking system includes an inner brake assembly 12 comprising an inner brake pad 14 suitably mounted to an inner brake shoe 16 the inner brake shoe 16 is suitably fixed to a drive mechanism 18 therefore which in the preferred embodiment.
