Ok, it's been a while since I've last posted with school and all, but I my chair is vibrating for some reason, when I press the breaks. I went up to Meineke to get an oil change (free w/ a coupon i got in an entertainment book). I also asked them to take my wheels off while they were at it, and my brakes pads and rotors where fine on the back seat ( assumed that it would be on the back axel ), and the front also looked fine. So, I asked the head mechanic there, and he said, "the most likely problem he could think of is that, the rotors needed to be rotated, and he said that right now it would be a "guessing game" to see which axel needs to be rotated; all 4 would probably needed to be rotated at 15 per rotor($60) and, $100 labor." So, I'm not sure if this guy is bsing me or what. But should I do it? If i were, I would want to do the back two rotors first, right?
