Frequently Asked Questions

Find answers to common questions about torque specifications

What is the brake rotor size for the 2005-2010 BMW M6?

The 2005-2010 BMW M6 is equipped with front brake rotors measuring 374mm x 36mm and rear brake rotors measuring 370mm x 24mm. These are ventilated and cross-drilled for improved heat dissipation and performance.

What type of brake pads are recommended for the BMW M6?

BMW recommends using genuine BMW brake pads or high-performance aftermarket equivalents that meet BMW's specifications. The front brake pads are part number 34116794886, and the rear brake pads are part number 34216794887. These pads are designed to work with the M6's high-performance braking system.

How often should the brake fluid be replaced on a BMW M6?

BMW recommends replacing the brake fluid every 2 years or 30,000 miles, whichever comes first. The M6 uses DOT 4 brake fluid, and it is crucial to follow this schedule to maintain optimal braking performance and safety.

What is the recommended procedure for bedding in new brake pads and rotors?

To properly bed in new brake pads and rotors, perform a series of 10-12 moderate stops from 35-40 mph, followed by 5-6 harder stops from 45-50 mph. Allow the brakes to cool completely before driving normally. This process ensures proper transfer layer formation on the rotors and maximizes braking efficiency.

Can I upgrade the brakes on my BMW M6?

Yes, the BMW M6 can be upgraded with aftermarket high-performance brake kits, such as those from Brembo or AP Racing. However, ensure the kit is compatible with the M6's specific dimensions and ABS system. Always consult a professional for installation to avoid compromising safety or warranty.
