Wilwood 200-11342 Thermlock Brake Caliper Piston 1.12" x 0.88"

The Wilwood 200-11342 Thermlock brake caliper piston is an advanced replacement component designed to significantly reduce heat transfer in high-performance braking systems. Measuring 1.12 inches in diameter with a 0.88-inch depth, this piston features Wilwood's exclusive multi-part thermal barrier technology.

Key Features:

• Thermlock multi-part design with stainless steel heat shield
• Coated aluminum shell construction for optimal heat resistance
• Reduces heat transfer by at least 25 percent compared to standard pistons
• Prevents seal crystallization and localized brake fluid boiling
• Minimizes caliper body distortion and extends service life
• Precision dimensions: 1.12-inch diameter x 0.88-inch depth

This innovative piston design creates an effective thermal barrier between the brake pads and the caliper body, protecting critical seals and brake fluid from excessive heat. By maintaining lower operating temperatures, the Thermlock piston helps ensure consistent brake performance and reduces maintenance requirements in demanding racing and performance applications.
