J.C. Whitney JF27160028 Rear Brake Caliper Left Driver Side OEM Replacement

The J.C. Whitney JF27160028 is an OEM-replacement rear disc brake caliper designed for the driver side (left-hand) position. Engineered to restore factory braking performance on the Ford F-250 and F-350 Super Duty, this caliper is a direct-fit replacement that installs in place of the original unit without modification.

How It Works:

The brake caliper is a critical component of the disc brake system. Each time the brake pedal is depressed, hydraulic pressure from the master cylinder actuates a piston inside the caliper, clamping the brake pads firmly against the rotor to slow or stop the vehicle. Over time, caliper pistons, seals, and boots wear out or corrode, reducing braking efficiency and safety — making timely replacement essential.

Key Features:

• Direct OEM Replacement — Designed to match original factory specifications for a precise, trouble-free installation
• Driver Side (Left-Hand / LH) — Rear axle, driver-side position
• 2-Piston Design — Matches the factory rear caliper configuration for the F-250/F-350 Super Duty
• Zinc-Coated Housing — Corrosion-resistant finish helps extend service life
• Steel Piston Construction — Durable piston material withstands heat and braking loads
• Inlet and Bleeder Port Size: 3/8 x 24 — Compatible with factory brake lines
• Piston Diameter: 1.77 in.

Common signs that a rear caliper needs replacement include brake fluid leaks, uneven or dragging brakes, pulling to one side under braking, or a spongy brake pedal. Replacing a failing caliper promptly helps preserve rotor and pad life, and maintains the full stopping capability of your Super Duty truck.
