Wilwood Piston - 1.38in x.84 Stainless Powerlite

This is a Wilwood 1.38 inch by 0.84 inch stainless steel caliper piston. It's a key component for rebuilding your Wilwood Powerlite calipers, ensuring they function correctly and provide reliable stopping power. Stainless steel is a good choice for pistons because it resists corrosion and wear, which is important in the harsh environment of a braking system.

When you're rebuilding your calipers, replacing worn or damaged pistons is crucial. These pistons are designed to fit Wilwood's Powerlite caliper series, maintaining the performance you expect from your braking system. Using the correct size and material ensures proper seal engagement and consistent hydraulic pressure transfer, which is what makes your brakes work.
