Wagner Brake BD125657PR Disc Brake Rotor - Rear

Premium rear brake rotor

The Wagner Brake BD125657PR is a premium rear disc brake rotor built for heavy-duty GM trucks and vans. It combines a cast iron, full-cast construction with a vented, smooth braking surface and a rust-resistant COAT+ finish for OE-style fit and consistent braking performance.

• COAT+ anti-corrosion finish helps protect the rotor surface from rust.
• Precision-finished surface reduces break-in time and supports proper pad bedding.
• Vented, smooth rotor design promotes stable braking performance.
• Cast iron, full-cast construction provides the mass and durability expected in a brake rotor.
• OE fit, form, and function for direct replacement service.

What this rotor helps address

• Brake pulsation caused by worn or uneven rotor surfaces.
• Corrosion on exposed braking surfaces.
• Extended pad bedding time after rotor replacement.
• Reduced braking consistency from a rotor that no longer meets service limits.

Installation notes and quality

Install as a direct replacement rotor for the listed rear applications. No machining or surface preparation is required before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Wagner Premium rotors are engineered to match OE fit, form, and function, and the BD125657PR part number is used throughout the catalog for identification.
