Keep your rear brakes clamping evenly with the Raybestos R-Line Remanufactured Semi-Loaded Disc Brake Caliper and Bracket Assembly (FRC11590) — a direct-fit rear-left Ford F-250 Super Duty brake caliper that also fits the F-350 Super Duty. It houses the piston and hydraulic seals that press the pads against the rotor when you apply the brakes; if the original has seized, is leaking, or drags, this remanufactured unit replaces it.
Remanufactured from OE cores: castings, guide pins, and brackets are inspected and reused, with all-new rubber and sealing components fitted. New leak-free service parts: seals, boots, bleeder screws, abutment hardware, banjo bolts, and O-rings are all replaced. EPDM70 rubber components for heat resistance, performance, and durability; silicone boots are used on heavy-duty applications where applicable. 100% pressure tested floating-type caliper with a cast-iron casting, a 48 mm (1.89 in) piston, and a 3/8-24 bleeder thread; materials match OE specifications. Country of origin: Mexico.
Fits (All engines): 2005-2007 Ford F-250 Super Duty and 2005-2007 Ford F-350 Super Duty. Sold individually as the rear-left unit; for even, balanced braking, replacing both sides as a matched pair is recommended.
