Wagner Brake CN4126SC Disc Brake Caliper - Front Left

Brake Caliper Overview

Wagner Brake CN4126SC is a disc brake caliper built with 100% newly manufactured components for consistent braking performance and corrosion resistance. It is a floating caliper with a cast iron body, a single 63.5 mm piston, and an included bleeder screw for service-ready installation.

Key Features

• Cast iron caliper body for durable hydraulic braking performance
• Floating caliper design with one piston for controlled pad movement
• 63.5 mm piston diameter for the specified brake application
• Coated finish helps resist corrosion
• Bleeder screw included with M10x1.5 thread size
• Pads are not included
• Mounting bracket is not included

Product Details

Wagner Brake CN4126SC is engineered as a direct replacement disc brake caliper for select Chevrolet S10, GMC Sonoma, Isuzu Hombre, Chevrolet Blazer, Buick Century, and Buick Regal applications. This part number CN4126SC is built from newly manufactured components rather than remanufactured cores, and the coated construction supports reliable service in brake hydraulic systems where corrosion control matters. This part cross-references Raybestos Brakes (e.g., FRC4126N) for the same application.

Common Replacement Issues

• Sticking or seized caliper movement
• Uneven brake pad wear from hydraulic imbalance
• Brake fluid leakage at the caliper assembly
• Corrosion on the caliper body or bleeder area

Installation Notes

Verify fitment by year, make, model, and front left position before installation. Confirm the bleeder screw thread size matches the brake system specification, and transfer or source any required pads separately since pads are not included. Bleed the hydraulic system after installation to remove air and restore pedal feel.

Quality Assurance

Wagner Brake supplies brake components designed for consistent performance across vehicle applications, and the CN4126SC uses newly manufactured parts with a coated finish for corrosion resistance.
