Master Cylinder Heat Shield – Protect Your Braking System from Excessive Heat

Protect your master cylinder and maintain safe, consistent braking performance with the Lava or Stealth Master Cylinder Heat Shield. In racing and custom builds, tight engine bays and high-performance exhaust components like headers and turbos can generate extreme heat near the master cylinder—one of the most critical components in your vehicle’s safety system. This rising heat can cause brake fluid to boil, leading to brake fade or even complete brake failure.

Whether you’re cruising on a Sunday drive or carving through corners at the track, boiling brake fluid is dangerous. The Master Cylinder Heat Shield helps prevent this by blocking radiant heat and reducing the risk of heat soak. Made from durable, heat-reflective volcanic rock-based material, this shield is resistant to chemicals, oil, and brake fluid, making it perfect for high-heat and harsh under-hood environments.

The patent-pending design allows for easy installation without disconnecting brake lines—no bleeding required. Stay safe, protect your brake system, and improve performance with the Master Cylinder Heat Shield.
