Wilwood Engineering designs and builds disc brake systems in Camarillo, California.

The complete brake system determines which individual components are appropriate.
Technical Details
- Manufacturer part number: 200-15451
- Outside diameter: 1.38 inches
- Overall length: 0.820 inches
- Piston construction: Thermlock
- Material: Aluminum - Stainless
Fitment & Compatibility
Match the existing piston and caliper documentation, including the overall depth and sealing arrangement. Vehicle make and model cannot identify this internal component on a modified brake system. The Thermlock assembly combines a stainless heat shield with a coated aluminum shell to reduce heat transfer toward the caliper body and fluid. Use the complete specified design rather than substituting by diameter alone.
