Product Details

Brembo’s Premium UV Coated OE Equivalent Rotor line is engineered as a direct OEM-style replacement with attention to fit, finish, and braking consistency. The solvent-free UV coating protects the disc, including the braking plate surfaces, while the high carbon cast iron material helps control noise and vibration for smoother pedal feel. Part number 09.D231.21 is specified for front brake service on 2000-2002 Mercedes-Benz SL500 and SL600 models, and it cross-references Centric Parts 128.35046 for the same application.

What This Rotor Helps Address

• Brake pulsation from worn or uneven rotors
• Corrosion on exposed rotor surfaces
• Noise and vibration during braking
• Reduced braking consistency from heat buildup
• Front brake service needs on Mercedes-Benz SL500 and SL600 models

Installation Notes and Tips

For best braking restoration, replace rotors and pads together. Brembo recommends pairing this rotor with NAO/Ceramic or Low Met brake pad formulations. Verify rotor dimensions, minimum thickness, and vehicle fitment before installation on 2000-2002 Mercedes-Benz SL500 or SL600 front brake positions. Use the included fixing screws during service where applicable.

Quality Assurance

Brembo manufactures braking components to OE-equivalent standards and uses UV coating technology to improve surface protection and durability. The rotor includes clear part-number and minimum-thickness marking for service reference, supporting accurate inspection and replacement decisions.
