Restore the power and precision of your braking system with this 9-inch Mastervac brake booster specifically selected for the Clio Group N. Engineered to meet the rigorous demands of motorsport, it ensures consistent assistance for perfect pedal modulation.
Essential for the maintenance of your braking system or the technical customization of your racing setup, this premium Mastervac is the key part to guarantee your safety during late braking on the track or rally stages with your sports vehicle.
In the world of competition, braking is just as important as engine power. By keeping a tired or leaking brake booster on your Clio 2 RS or Clio 3 RS, you accept a hard brake pedal and unpredictable loss of assistance. Without replacing it with this 9-inch Mastervac model, you risk dangerous increases in braking distances and an inability to lock the wheels during emergency maneuvers. Don't let a weakened braking system compromise your stage times and safety inside your race car.
The absence of reliable braking assistance causes increased driver muscle fatigue and a total loss of pedal feel. By neglecting this core safety component, you lose the confidence needed to attack intense braking zones, leading to an immediate drop in performance.
This servo-brake Mastervac (9 inches) is the standard for Group N and Renault Sport builds. Its optimized size provides the ideal compromise between braking assistance and pedal feedback. Whether you are overhauling your braking system or performing a technical customization for rally use, this component ensures stable vacuum and immediate response. It is the perfect partner for a high-performance master cylinder to stop your Clio RS with precision.

How do I know if my Mastervac is failing?
An unnaturally hard brake pedal, a hissing sound when pressing the pedal, or engine RPM fluctuations when braking are signs of a punctured internal diaphragm or a vacuum leak.
Is it compatible with my original Clio 2 RS setup?
Yes, this 9" Mastervac meets the mounting specifications for sports and Group N configurations, offering superior reliability compared to mass-produced series parts.
Performance starts with braking you can count on. Trust the expertise of Optimiz Access to provide the brake booster essential for your sports car's survival in extreme conditions.
