rotor problem i had my friend came over to look at my left rear brake... since im retarted when it comes to that. anyways he said that the rotor itself when it last got changed that the rotor was never rotated and just started to glaze over and over a little time the friction starts to make a high squeal b/w the pad and rotor, which explains after 10-15 min. of driving a loud high squeak comes from the back rear. is it as easy as it sounds just to rotate the rotors, or does that sound like b.s.

They call it 'turning' the rotors. It is a machining process that slices off material to leave a smooth surface. If the rotors get too thin then they cannot be turned. It is so easy to just throw pads on that whoever did them last either took the easy way out or did not want to spend the time or money to get the job done right. You may have to replace the rotor. Any reputable brake place can quote the thickness specs that are required to let you 'turn' the rotors and re-use.
The discard thickness is on the rotor, so you should be able to see if it is past the discard or if there is still some thickness to which it can be reused. Turning rotors is fairly easy, so if you have access to a brake lathe through family/friends then just see if you can get someone to give you a hand and possibly save some $$. If not, get some new rotors and pads, and do the job yourself. Still saving $$.
