well ive sat on my ass too long and now the problem has finally reared its ugly head. My front brakes had a little metal to metal contact this afternoon, i can see the result of it forming on my rotors. i get paid friday and plan to replace them then. in the meantime, am i going to be doing any hardcore damage to my rotors between now and then? ive been downshifting alot more than normal to save what little is left of the pads. appreciate the input as always
maybe you could get your rotors re-grinded, not too sure if that helps, my BMW was the first car I got where I had to do any brake work: recently got new pads, brake fluid, and rotors, but everything was shot so I HAD to replace it all.

thx guys. yeah i checked the rotors and those are all good not warped or nething because im experiencing no shaking or shimmying when i come to a stop. the prob is pads which is an easy fix i will be doing tomorrow.
Yes, the rotors can be resurfaced/cut/"reground.."(never heard that one before), however in actuality the oem bmw rotors are a softer material than most of you think meaning the pads and rotors wear out at the exact same pace. If you do your own brake jobs and done other cars as well you'd notice your rotors compared to other manufacturer rotors have a big lip on them, which is caused by what i just said before. Most german car companies do this, where the pad and rotor wear out at the same time, and thus have to be replaced EVERY time you do a proper brake job according to manufacturer recommendations. Also if you plan on replacing just the pads without replacing or resurfacing the rotors at the least, it's not a good idea. The reason we resurface rotors is because you want a new mating surface with the new pads, and yada yada yada bottom line, not good for the pads and in some cases it makes noise.
So to answer your question, sure you can resurface the rotor, will it be under specs? i'm pretty sure it will be. Does it matter? sort of, the thinner the rotor the more likely it will become warped. Are you willing to spend the extra few bucks and do it properly? up to you
