Brake discs minmum wear limit?

[Flex]

Does anybody perhaps know what the minimal wear limit on brake discs are? This info would be relative to a 120i model. :=):

I looked around on google, no particular dimensions found. :thumbdo:

Thanks guys! :ty:

normally about 2mm less than new total per disk...

use realoem to find the part number then google that to find new dimensions...
