Brembo 09937421 High Carbon Brake Rotor with UV Coating

The Brembo 09937421 is a high-carbon cast iron brake rotor engineered to deliver superior braking performance, reduced vibration, and enhanced driving comfort. Manufactured with the same precision and quality standards that make Brembo the trusted choice of leading automakers worldwide, this rotor is designed as a direct OE replacement that meets or exceeds original equipment specifications.

High Carbon Metallurgy: Constructed from premium cast iron with elevated carbon content, this rotor minimizes noise and vibration while maximizing heat dissipation and thermal stability. The optimized metallurgy reduces the risk of distortion or cracking under extreme braking conditions, delivering reliable, fade-resistant performance.

Advanced Corrosion Protection: Features Brembo's signature UV coating that protects the entire rotor surface against corrosion, ensuring lasting performance and a clean, refined appearance even after extended use. The environmentally friendly, solvent-free coating allows for installation right out of the box.

Key Features:

• Easy Check Visual Indicators: Two visual wear indicators allow you to check the rate of brake disc wear at a glance
• Pillar Venting Technology (PVT): Exclusive ventilation system improves cooling capacity and increases disc strength by over 40% compared to conventional vane designs
• Electronic Balancing: Each rotor undergoes strict electronic testing to ensure perfect balance and minimal runout right out of the box
• Complete Hardware Kit: Includes fixing screws and all necessary hardware for simpler, more efficient, and safer installation
• ECE R-90 Compliance: Meets European safety legislation standards for quality and performance

For optimal braking performance and longevity, Brembo recommends replacing rotors and brake pads together. This rotor is compatible with Brembo's NAO/Ceramic or Low-Metallic brake pad formulations.
