Nugeon 99-17958B rear left brake caliper for the 2008-2012 Ford F-250 Super Duty and other vehicles clamps the brake pads against the rotor to slow the wheel. It is a remanufactured disc brake caliper of the floating type.
Pulling to one side under braking, brake fluid around the caliper or a pad worn more on one side can mean a sticking or leaking caliper. Those signs alone do not prove the caliper is at fault, since a collapsed brake hose can pull the vehicle the same way.
It is a direct-fit replacement brake caliper for the 2008-2012 Ford F-250 Super Duty and the 2008-2012 Ford F-350 Super Duty. This listing is one caliper for the rear left; the rear right is a separate part, and the two rear calipers are normally done at the same time.
