The Brake Disc on GMC Jimmy automobiles is a part of the disc brake system, which is used as the rotating component on which forces the brake pad to apply pressure in order to reduce the speed or stop the auto vehicle. Attached to the axle or to the hub of the car, the rotor is an integrated part of the rotating wheel; squeezed by the hydraulic calipers, the pads squeeze the rotor during braking. Over the years, Brake Discs used on GMC Jimmy vehicles has been of different designs such as the solid and the vented type. Vented rotors, with such components as cooling fins, heat more effectively than the solid rotors which are characteristic of compact or non-sport model cars. Virtually all rotors are made from cast iron with some designs opting for use of composites for enhanced performance. It is crucial to inspect rotors more often since they can be scored, warped, or have a higher runout that affects braking.
