Wagner Brake BD126457PR Disc Brake Rotor - Rear

Wagner Premium Rear Brake Rotor

The Wagner Brake BD126457PR is a premium disc brake rotor built for rear applications on a range of full-size GM SUVs and trucks. It combines a cast iron, full-cast construction with a rust-resistant COAT+ finish for OE-style fit, form, and function.

• COAT+ anti-corrosion finish helps protect the rotor surface.
• Precision-finished surface reduces break-in time and supports proper bedding.
• Vented, directional rotor design for consistent braking performance.
• Cast iron, full-cast construction for a direct replacement profile.
• Fits rear brake applications on multiple Cadillac, Chevrolet, and GMC models.

• Corrosion on exposed braking surfaces.
• Extended break-in time after rotor replacement.
• Fitment issues from non-OE-style rotor dimensions.
• Reduced braking consistency on rear axle applications.

Installation Notes and Tips

Install as a rear disc brake rotor replacement for the listed applications. Wagner states no machining or preparation is required before installation, and the precision finish supports proper pad bedding. For balanced braking performance, pair the rotor with matching Wagner brake pads and calipers where applicable.
