Caliper GM D52 2.75in Piston 1.25 Rotor

The Caliper GM D52 2.75in Piston 1.25 Rotor by WILWOOD is a precision-engineered disc brake caliper designed for General Motors D52 brake platforms, making it an essential upgrade for street performance and track-focused vehicles. Built for automotive enthusiasts who demand superior stopping power and modulation, this caliper transforms your braking system with professional-grade engineering. Whether you're upgrading an older GM muscle car, a street rod, or a weekend autocross competitor, this WILWOOD component delivers the hydraulic control and mechanical reliability that separate competent brakes from exceptional ones.

This caliper features a 2.75-inch piston diameter that generates substantial clamping force while maintaining predictable brake modulation across a wide range of pedal pressures—critical for both street driving and spirited performance. The 1.25-inch rotor compatibility indicates optimized pad sweep and thermal mass management, allowing consistent friction coefficients even during extended braking events. WILWOOD's manufacturing standards ensure tight tolerances in the piston bore, seal grooves, and mounting surfaces, minimizing brake fade and extending pad life. The compact footprint (6.1 x 4 x 8.9 inches) and 4.35-pound weight make it suitable for applications where space constraints or weight reduction matters without sacrificing stopping authority.

Mechanics and fabricators installing this caliper on GM D52-equipped vehicles will appreciate the direct fitment design and standardized mounting geometry that simplifies bracket selection and brake line routing. Compatibility spans multiple GM platforms from the 1960s through early 2000s, including Chevelle, Camaro, Corvette, and truck applications with D52 spindle or caliper carrier configurations. Installation requires proper brake system bleeding, pad-to-rotor clearance verification, and line pressure testing to ensure safe operation. This WILWOOD component is ideal for restomod projects, street performance builds, and vintage racing where stopping precision directly impacts driver confidence and safety.
