This single - line master cylinder features a 3/4' bore. It's designed for braided brake line fittings and uses DOT 5 brake fluid. Specifically, it is a perfect fit for Margay Brava karts, ensuring reliable braking performance.

To use this master cylinder, first make sure it is properly installed on your Margay Brava kart. Connect the braided brake line fittings and fill it with DOT 5 brake fluid. When operating the kart, the master cylinder will transfer the pressure from your brake pedal to the brakes. As for maintenance, regularly check the brake fluid level. If it's low, top it up with DOT 5 brake fluid. Also, inspect the master cylinder for any signs of leakage or damage. If you notice any issues, replace the part immediately to keep your kart's braking system in good working condition.
