Brake Rotor Clamp Secures the rotor to prevent it from being knocked around and allowing rust and dirt to fall between the hub and rotor. Each 3” jaw is specially designed to firmly hold the brake rotor on the hub while brake pads are being installed to the caliper and the sides are being serviced. The center of the clamp jaws are formed down towards each other like teeth. The outsides are still pointing straight out the front of the clamp. The teeth bite into the threads of the lugnut stud on the hub while the outside point hold the rotor firmly in place 750 Yes -
