The Wilwood PS-1 Brake Caliper is a compact, lightweight performance brake component designed for high-efficiency braking systems. Constructed from cast aluminum, this caliper weighs only 0.93 pounds, offering a sleek low-profile design that minimizes weight without sacrificing strength. It features two stainless steel deep cup pistons that reduce heat transfer from the 0.30-inch thick brake pads to the brake fluid, enhancing thermal management during intense braking. The caliper employs high-temperature square piston seals to ensure optimal piston retraction and consistent pad contact. Internal crossover brake fluid passages eliminate external crossover tubes, simplifying installation and improving fluid flow. Overall, the PS-1 caliper delivers reliable, high-performance braking suitable for demanding applications.
Designed for rotors with diameters from 6.00 to 9.00 inches, the Wilwood PS-1 caliper fits a variety of performance vehicles requiring a passenger side, 2.5-inch lug mount setup. Its versatile design makes it suitable for track days, street use, or racing applications where precise braking response and heat management are critical. This direct bolt-on caliper is engineered for easy installation and compatibility with existing Wilwood brake systems. The kit includes the caliper itself, with internal crossover passages for efficient brake fluid flow, ensuring consistent performance under high-stress conditions. Ideal for enthusiasts seeking a durable, lightweight upgrade for improved braking performance.
