Detailed Description

Part number 09.C128.33 is a rear disc brake rotor engineered for Mercedes-Benz AMG GT, AMG GT 63, AMG GT 63 S, AMG GT C, AMG GT R, AMG GT S, S63 AMG, S65 AMG, and Maybach S650 applications listed in the fitment data. The rotor measures 360 mm in outside diameter with a 67 mm center hole diameter, 26 mm nominal thickness, and 24 mm discard thickness. Its vented construction and slotted X drilled surface are suited to performance braking systems that need controlled heat dissipation and repeatable pedal response. This part cross-references Mercedes-Benz OE numbers 222 423 20 12 and 92319805 for the same application.

Common Issues This Rotor Can Address

• Brake pulsation caused by rotor wear or thickness variation.
• Reduced braking consistency from heat buildup in performance use.
• Surface corrosion on an aging rear rotor.
• Noise or uneven pad contact from a worn braking surface.

Installation Notes and Tips

Verify rear fitment against the vehicle listing before installation. Confirm rotor dimensions, hub fit, and brake system configuration match the application. Inspect pads and related brake components during replacement to ensure even contact with the new rotor.

Quality Assurance

Brembo PRIME is positioned as a premium rotor line with OE-style engineering focus and application-specific fitment coverage.
