A brake pad wear measuring system is for use a floating caliper disc brake system including a piston supporting an inner brake pad and a floating caliper supporting an outer brake pad, wherein the piston and floating caliper move toward each other along a braking axis in response to application of the brake system so that the brake pads engage and apply a braking force to a brake rotor. The brake pad wear system includes a sensor mounted on the floating caliper and movable with the floating caliper along the braking axis and an actuator mounted for movement with the piston along the braking axis. The sensor and actuator move toward each other in response to application of the disc brake system. The distance that the sensor and actuator move toward each other in response to application of the disc brake system increases an amount that is equal to the total wear of the inner and outer brake pads. The sensor is responsive to the presence of the actuator to provide a signal indicative of brake pad wear.
