I could really use some advice. My girlfriend somehow ran her rear brakes down so far that the pad fell out of the bracket and the piston was actually worn down from braking. Guess I should see her more often. Lol. Anyways I replaced both rotors, pads and the bad caliper and got it all buttoned up I got fluid from the new caliper while bleeding but can't seem to get any pressure to the rear brakes. They aren't grabbing at all. Front brakes seem fine. Also I don't know what the Brake, VSC and Trac lights are about. Thought they'd go away after changing them. I keep things simple and try to stay away from my computer controlled stuff. Never had these type of issues before. Thanks for any helpful advice
