Product Details

Wagner Brake CN4124SC is engineered as a replacement disc brake caliper for front left fitments across GM passenger cars, wagons, and light trucks. The cast iron construction and coated surface support dependable hydraulic operation while helping protect the caliper from rust in everyday driving conditions. This part number, CN4124SC, is used across a broad range of applications including Chevrolet Caprice, Cadillac Fleetwood, and Buick Roadmaster fitments.

This part cross-references Cardone Reman 18-4021 and Raybestos Brakes FRC4124N for the same application.

What It Helps Address

Sticking or seized caliper movement
Brake fluid leakage at the caliper
Uneven braking caused by worn hydraulic components
Corrosion on the caliper housing or bleeder area
Reduced braking response from a failing original caliper

Installation Notes

Verify the vehicle’s front left fitment, piston size, and brake system notes before ordering. Some applications require 11-inch or JB1/JB3 system matching, so confirm the original caliper configuration against the listed fitment data. Bleeder screw thread size is 3/8-24.

Quality Assurance

Wagner Brake manufactures this caliper with newly produced components and a coated finish to support reliable service life and consistent braking performance.
