Detailed Product Description

This Brembo disc brake rotor is crafted from high carbon steel, providing a balance of strength and thermal conductivity essential for effective braking. The drilled braking surface enhances ventilation, allowing heat to dissipate quickly during heavy braking, which helps maintain consistent stopping power. The UV coated finish protects the rotor from rust and corrosion, extending its service life even in harsh environments. With a solid rotor design, 295 mm outside diameter, and 44 mm height, this rotor meets the precise specifications required for select Infiniti and Mercedes-Benz vehicles.

The rotor’s 5-hole mounting pattern and 67 mm centering diameter ensure a secure fit, while the included fixing screws simplify installation. Maintaining the nominal thickness of 10 mm and not going below the minimum thickness of 8.3 mm is critical for safe operation. The specified torque of 130 Nm should be applied during installation to guarantee proper seating and performance.
