A disc brake assembly is provided that includes a camshaft extending from a slack adjuster. A disc brake rotor and a brake caliper bridge having an outer plate and an inner plate are provided. A brake caliper carrier is provided with an outer brake pad contained by the brake caliper carrier and an inner brake pad contained by the brake caliper carrier. A cam carrier having two openings is provided along with a pusher plate having a first surface in contact with the cam and a second surface in contact with the inner brake pad. A first and a second slide pin each extend through an opening in the cam carrier and an opening in the pusher plate and an opening in the inner plate of the brake caliper bridge and into the brake caliper carrier. A cam is mounted onto the camshaft such that rotation of the camshaft will rotate the cam, and the brake caliper bridge inner plate having a surface in contact with the cam. The brake caliper bridge outer plate having a surface in contact with the outer brake pad, such that upon rotation of the camshaft and the cam, the pusher plate adjusts the axial position of the inner brake pad and the brake caliper bridge outer plate adjusts the axial position of the outer brake pad, actuating the brake.
