Wilwood D52-R 2.75in Piston 0.810in Rotor Aluminum Brake Caliper 120-15610

If you're running a classic GM platform and demand consistent, fade-free braking under sustained track conditions, the Wilwood D52-R delivers the stopping power and thermal stability that separate competitive lap times from mediocre ones. This single-piston floater caliper reduces unsprung weight while maintaining the clamping force needed for road racing, autocross, and street performance driving. The forged aluminum construction with Type III hard anodize resists corrosion and heat cycling, ensuring reliable performance season after season.

Designed as a direct bolt-on replacement for 1968–96 GM passenger vehicles and trucks, the D52-R integrates seamlessly into your existing brake system without fabrication. The centrally located fluid port and dual-bleeder design simplify bleeding and maintenance, while the stainless steel piston resists scoring and extends service intervals.
