Wilwood 200-15451 Thermlock Brake Caliper Piston 1.38" x 0.82"

The Wilwood 200-15451 Thermlock brake caliper piston is an innovative replacement component designed to significantly reduce heat transfer in high-performance braking systems. Measuring 1.38 inches in diameter with a 0.82-inch depth, this piston features Wilwood's exclusive multi-part thermal barrier technology.

Key Features:

• Thermlock multi-part design reduces heat transfer by at least 25 percent
• Stainless steel heat shield effectively blocks thermal energy transmission
• Coated aluminum shell construction for optimal strength-to-weight ratio
• 1.38-inch diameter x 0.82-inch depth dimensions
• Prevents seal crystallization and brake fluid boiling
• Reduces caliper body distortion and extends service life
• Compatible with Wilwood disc brake calipers

By creating an effective thermal barrier between the brake pads and caliper internals, this Thermlock piston maintains lower operating temperatures, protecting critical seals and brake fluid from heat-related damage. The innovative design helps maintain consistent brake performance and pedal feel while extending the service intervals of caliper components.
