Clamp the brake pads firmly against the rotor with the Nugeon Remanufactured Disc Brake Caliper 99-17938A. This caliper houses the hydraulic pistons that press the pads under braking, and it drops in as a direct-fit replacement for the 2005-2012 Ford F-350 Super Duty and the 2011-2012 Ford F-450 Super Duty (All engines). Fully remanufactured, it is a cost-effective way to replace a worn or leaking original.
Signs that a caliper may need replacing include a brake pull to one side, uneven pad wear, a sticking or dragging brake, or fluid seeping past a piston seal. If a failed caliper is the cause, this unit replaces it. Bracket mounting bolts are not included; consult the vehicle service information for the correct fasteners and whether they may be reused.
