E9X M3: How many brake pad wear sensors on board?

davem3fan · 09-24-2009, 03:30 PM

See subject for simple question.

Are there brake pad wear sensors on each corner,
or just on both front brakes and the USA passenger side rear?

Thanks!

I believe brake sensors are on the each pass sides. So one in front, one on the back.

The latter (in bold). You can clearly see (and feel) the wires coming out of the calipers if you don't believe me Isugoo

I don't have an "untouched" reference car to compare...
Somehow I convinced myself that both rears have the sensors.

'08s don't. Can't say for sure on '09s, but I sincerely doubt it.

The '09s are the same, both fornt and the rear right.
