A coaxial helically actuated disc brake is provided. The coaxial disc brake includes a pressure plate that is rotationally actuated and helically guided by a brake support structure to axially engage a brake pad carrier with a rotor. The pressure plate, brake pad carrier and rotor are all coaxial with the rotating member upon which the coaxial disc brake acts. Multiple concentric pressure plates and brake pad carriers can be used. Multiple brake pad carriers acting as stators can be coaxially stacked between multiple coaxial rotors. A low friction device, material or element can be placed between the pressure plate and brake pad carrier to allow for easier disengagement of the brake.
