Wilwood Piston - 1.25in x 1.05in SS

When you're rebuilding your Wilwood brake calipers, getting the right internal components is key to restoring their performance. This 1.25-inch by 1.05-inch stainless steel piston is designed to be a direct replacement for specific Wilwood caliper models, helping to ensure your braking system operates as intended.

Crafted from stainless steel, this piston offers good resistance to corrosion and wear, which is important for maintaining a reliable seal and smooth operation within the caliper bore. Having the correct piston size is critical for proper brake fluid pressure transfer, which directly impacts your vehicle's stopping power and feel. Replacing worn or damaged pistons is a necessary step in a caliper overhaul to prevent leaks and ensure consistent braking performance.
