So here's how this stuff got started; Car has a slight wobble, get it checked out while out of town, they say it may just need an alignment but it's inconsistent so they don't know what's going on. Get about halfway back from a couple hundred mile road trip and the wobble has gotten more consistent but when I get it checked out they still can't figure it out. Get an alignment. It still wobbles, but now it's worse. Finally get home and get it to a mechanic friend and he immediately diagnoses it as a seizing caliper. We get new calipers, rotors and brakes, just to be safe. Well we change all of these and bleed the brakes. The first time we bleed them it doesn't work, air in the lines. Okay I'm new at this, maybe it's me. We bleed them again. This time they work, but I have to push the pedal three times to build pressure. First time no reaction, second a slight reaction, third time it brakes like it should: like it has brand new brakes. It wouldn't build pressure at all if it were the master cylinde, would it? I'm so baffled and I don't want to take her to a shop if this is something I can do myself. My friend thinks it may be the ABS system itself. I'm really stumped.
