There's an intermittent squeaking/squeeling coming from my wheels all the time and I'm not sure what it exactly is. It gets slightly worse for about a second when I put on the brakes. But I don't think it could be the brakes considering I got new pads and calipers on the back, and my front ones have new pads also. The rotors are fine too. Does anybody have another hunch to what it could be? Maybe it is the brakes and I'm just crazy?
