Detailed Description

Brembo 09.A945.33 is a premium front brake rotor engineered for performance-oriented Mercedes-Benz platforms that demand precise pedal feel and dependable heat control. The high carbon cast iron rotor helps manage vibration and thermal stress, while the slotted X-drilled face supports more consistent contact under repeated braking.

What This Rotor Helps Address

• Brake pulsation caused by rotor wear or uneven friction surfaces
• Reduced braking consistency from heat buildup during spirited driving
• Corrosion on exposed rotor surfaces
• Noise or vibration associated with worn front rotors
• Loss of braking confidence on AMG performance vehicles

Installation Notes and Tips

Compatible With front brake positions only. Verify rotor dimensions before installation: 360 mm outside diameter, 36 mm nominal thickness, and 33 mm discard thickness. Confirm the 67 mm center hole diameter and 5-lug fitment against the vehicle’s brake package before service. For best results, inspect pads, caliper hardware, and hub condition during rotor replacement, and follow the vehicle manufacturer’s bedding procedure after installation.
