2013 M6 brake wear
New to me 2013 F12 with 31k miles, recent inspection shows lip on rear rotors but fronts are fine. Pads low all around. I'm used to fronts wearing much faster than rears, but this seems pretty consistent or maybe even rear biased wear. Is this typical?
Thanks |

At 31k, there's a chance the rears were never replaced since new.

Put it this way. When TCS is on, and you stomp on the gas from a stop, you got a ton of wheelspin, but the car doesn't go anywhere. It's not the brakes that's not causing you not to move, it's the inability for the differential to apply the power correctly.

thanks for the clarification, i did not know how the M6 applied it. i know in some volkwagen platforms they just apply the brakes to the side that is slipping to pull it in.

Sorry to slightly hijack, but does anyone remember off hand how many millimeters brakes need to be before BMW will replace them under maintenance? Car is telling me 1400 more miles on my rears, but at this rate I think my maintenance will be expired by the time I get 1400 in. Thanks

Take a hard curve with traction control left ON; you can feel the car applying brakes momentarily to keep the car in control. You can feel this especially during coasting on the curve. Turn the traction control OFF but leave the MDM on, and take the same curve. You won't feel the braking anymore. Coasting around the curve will be smooth with no felt braking. Turn MDM OFF, and you're on your own. |

The 1400 estimate is based a pad wear sensor on a single corner. Face on my experience the sensors are reasonably accurate. I typically run it down to zero or even a few hundred pass the indicator.

If you were to install brand new pads and kept the worn sensor you will still have a check brake light on the dash I believe that 1400 or what ever number is an approx installed by the BMW tech after he measures the thickness of the pad
