PS-1 Caliper 1.00/.20 L/H

The PS-1 Caliper 1.00/.20 L/H from Wilwood is a precision-engineered brake caliper designed specifically for automotive enthusiasts and professional mechanics focused on high-performance braking systems. This left-hand caliper is ideal for vehicles requiring upgraded stopping power, particularly in track-focused builds and custom brake system upgrades where OEM components may fall short.

The PS-1 caliper features a 1.00-inch piston diameter with a 0.20-inch stroke, providing a balance of mechanical advantage and modulation for both aggressive braking and smooth stops. Its single-piston design reduces weight while maintaining hydraulic efficiency, and the left-hand orientation ensures proper fitment on the appropriate side of your brake setup. Wilwood's stringent manufacturing standards guarantee tight tolerances and consistent bore quality, minimizing fluid bypass and maximizing pad pressure for fade-resistant performance.

This caliper is particularly favored by road-course competitors and custom builders who demand reliable braking performance under demanding conditions. The compact 4.45 x 3.55 x 6-inch footprint and lightweight 1.17-pound construction make the PS-1 Caliper an excellent choice for weight-conscious builds, where unsprung mass directly impacts handling and braking feel.
