J.C. Whitney SET-JL27160003 Rear Brake Caliper OEM Replacement Set - 2-Wheel Kit

The J.C. Whitney SET-JL27160003 is a complete rear brake caliper replacement kit, sold as a 2-wheel set that includes both the driver-side and passenger-side calipers. Designed as a direct OEM replacement, this kit restores proper braking performance to the rear disc brake system.

How It Works:

A brake caliper is a critical component of the disc brake system. It applies hydraulic pressure to the brake pads, forcing them against the brake rotor to generate the friction needed to slow or stop the vehicle safely. Worn or seized calipers can cause uneven pad wear, pulling, reduced stopping power, and brake drag — making timely replacement essential.
