Wilwood Piston Thermlock - 1.62in x .88in

When you're rebuilding your Wilwood calipers, especially for track or performance use, managing heat is key. This piston thermlock is a small but important piece that helps keep excessive heat from transferring into your brake fluid. It's designed to sit between the piston and the brake pad, acting as a thermal barrier.

This specific thermlock measures 1.62 inches in diameter and 0.88 inches in thickness, fitting a range of Wilwood caliper pistons. By reducing heat transfer, it helps prevent premature brake fluid boil-off, which can lead to a spongy pedal and reduced stopping power during demanding use. It's a well-built component that's part of a larger system to keep your brakes performing reliably.
