A worn or spongy brake master cylinder immediately compromises braking precision and track safety. This high-performance brake master cylinder is strictly identical to the official item from the Renault Sport catalog for the Clio 3 X85 Cup. It guarantees a firm, consistent, and ultra-responsive pedal feel to fully exploit your braking system's potential in competition as well as during track days.
Under hard driving or track conditions, the braking system endures extreme thermal and pressure stresses. Over time, the internal seals of a brake master cylinder wear out, soften, or leak fluid internally. Keeping a fatigued hydraulic unit on a race or track car leads to immediate consequences:
Engineered to meet the extreme demands of the Renault Clio 3 X85 Cup race car, this sports brake master cylinder features a bore diameter specifically calibrated to efficiently feed multi-piston calipers. It restores a sharp pedal attack and absolute hydraulic control.
Manufactured to motorsport and aerospace quality standards, it withstands the extreme heat generated by high-boiling-point racing brake fluids (such as RBF fluid).
This component directly originates from the Cup (X85) competition specs. On a standard Renault Clio 3 RS (Phase 1 and Phase 2), its installation is highly popular among enthusiasts seeking to eliminate the overly soft factory pedal feel, especially during trackday conversions.
To maximize the performance of this hydraulic component, using high-performance racing brake fluid is strongly advised. You can find compatible racing fluids and braided lines among the complementary and related products available at the bottom of this page.
Yes, replacing the master cylinder requires a complete brake circuit bleed using a pressure bleeder to remove any air bubbles from the unit and calipers.
Since 2010, Optimiz Access has selected the finest technical parts, braking components, and competition accessories for performance car enthusiasts. We prioritize proven quality parts to maintain driving pleasure and track safety.
