30K Need new rear pads?
Sensor just popped on the rear brake pads at 30K miles...no warning from the computer which was telling me 80K...
Anyone had their brakes wear down so quickly? (I don't track the car). Anyone recommend a certain replacement pad? Thanks |

Did you check the pad thickness to confirm? If not it could just be a faulty wear sensor.

I have 62K on my car and a recent service check didn't indicate the mm left but the tech said both front and rear pads were fine.

The ESP definitely uses the brakes (mainly the rear) to keep you pointing in the right direction. If the rears have worn before the fronts then its likely from the ESP running overtime. I am 99% certain the M2/3/4 dont use brake based torque vectoring as you suggest. The M2/3/4 have the active M diff which can accomplish a similar result without using the brakes. This is also what makes the car tail happy. If you brake the inner wheels the car will want to rotate more into the corner, if you lock the rear wheels with the diff you accomplish the same thing by sending more power to the outer wheels. The downside to brake based TQ vectoring is that you "slow" the car down (not in lap times as it allows you to corner harder than you otherwise could) and it will overheat your brakes. The downside to a locking diff is that the inside wheel will also be sped up and want to push the rear end wide into a drift (if you use to much power). TO OP used MDM and slide around a lot?

This is very interesting because I have been running on some badly worn rear conti tires....so the esp may have been inadvertently active causing the brake wear...

But check em as the wear system is screwy.

I can see them wearing out at 30k, depending on the driving conditions. |

ESP is another matter and there ofc the brakes are used. Its a subtle distinction, one is to keep you from ducking up (ESP/ stability control) the other is to make you faster round a corner (torque vectoring).

Well, I just did a 3500 mile trip....with badly worn tires...so maybe the stability control at the expense of the rear brakes saved my life a couple of time without me knowing....????
