The Advantages of Hub-Mounted On-the-Car Brake Lathes Compared to Caliper-Mounted Designs

The effect of the mounting design to the vehicle for on-the-car brake lathes is examined for hub-mounted lathes that mount only to the rotor hub and for caliper-mounted lathes that mount to the caliper mounting surfaces on the steering knuckle. The comparison between the two designs concentrates on three major considerations: quality assurance, machine tool design and ease of operation. The advantages of the hub-mounted design are emphasized especially the ability of the hub-mounted design to ensure that the refinished rotor friction surfaces meet all O.E.M., and geometric tolerance requirements for proper braking and vehicle performance.
