Wilwood PS-1 Caliper with 1.12-inch Pistons for High-Performance Braking

Description

The Wilwood PS-1 Caliper (Part Number 120-8373) offers a compact and lightweight solution for demanding automotive braking needs. Weighing only 0.93 pounds, this caliper combines durability with a sleek low profile design, making it ideal for applications where space and weight are critical. Crafted from cast aluminum, it provides the strength necessary to withstand high-performance conditions without adding unnecessary bulk. The PS-1 features two stainless steel deep cup pistons measuring 1.12 inches in diameter, which help minimize heat transfer from the 0.30-inch thick brake pads to the brake fluid, enhancing overall brake efficiency and reducing fade during intense driving. It employs high-temperature square piston seals to maintain piston retraction and ensure consistent braking performance under thermal stress. Internal crossover brake fluid passages eliminate external crossover tubes, simplifying installation and reducing potential leak points. Designed to fit rotors with diameters from 6.00 inches to 9.00 inches and thicknesses between 0.15 inches and 0.20 inches, the PS-1 Caliper is suitable for a range of performance applications. Whether upgrading a classic car or building a custom race vehicle, this caliper delivers reliable stopping power with a focus on heat management and durability.
