Wilwood 200-9615 Thermlock Brake Caliper Piston 1.62" x .88"

The Wilwood 200-9615 Thermlock brake caliper piston is an advanced replacement piston designed to significantly reduce heat transfer in high-performance braking systems. Measuring 1.62" in diameter with a .88" depth, this piston utilizes Wilwood's innovative multi-part construction to create an effective thermal barrier between brake pads and caliper components.

Key Features:

• Thermlock technology reduces heat transfer by at least 25 percent compared to conventional pistons
• Multi-part design incorporates stainless steel heat shield and coated aluminum shell
• Prevents seal crystallization and localized brake fluid boiling
• Reduces caliper body distortion and extends piston bore service life
• Precision-sized at 1.62" diameter x .88" depth for proper fitment

By maintaining lower operating temperatures, this Thermlock piston helps preserve caliper seals and brake fluid integrity during demanding track use or heavy-duty applications. The stainless steel shield configuration creates a thermal break that protects critical caliper components from excessive heat, ensuring consistent brake performance and extended component longevity.
