Wilwood Master Cylinder Cap with Electronic Fluid Level Sensor for 7-10.7 oz Reservoirs 330-12646

Brake fluid monitoring isn't a luxury—it's a critical safety measure that prevents system failures mid-race or mid-drive. This Wilwood Master Cylinder Cap integrates electronic fluid level sensing directly into your remote reservoir, giving you real-time visibility into brake condition without guesswork. For serious racers and high-performance builds, knowing your fluid status before it becomes a problem is the difference between finishing the day and limping home.

The cap is engineered from high-melting-point nylon that resists engine bay temperatures and UV degradation, while its internal diaphragm sealing ensures your brake system stays pressurized and protected. Installation is straightforward—it connects to standard 12V DC automotive terminals, making integration into your wiring harness simple. As a direct replacement for Wilwood's remote reservoirs, fitment is guaranteed with no modification required.
