I bought a 2001 Mustang GT that was sitting for over a year, then it sat in my driveway for almost another year. I finally put it on the road and about a week or so ago the front passenger side caliper got stuck. So I changed it and bled it. After that the brakes went to the floor. I've bled every caliper numerous times in correct order assuming it was air in the lines. I ended up getting a little peddle back after many bleeds, but it was still very low and squishy. Then my driver side caliper started to stick, so I changed that too and bled all the lines again. Still had very little peddle. The next day after a 15min drive I smelt brakes. The driver side was very hot, the passenger side was kinda hot. Thought maybe I got a bad remanufactured caliper or possibly a internally damaged hose line. Actually I was quite certain it was the brake hose because what are the odds I got two bad calipers.. So I got two new brake hoses, put it on. Pumped it a few times and drivers side caliper got stuck again. I opened the bleeder and expected it to release, but it didn't unstick without me banging on it. Then I thought it must be a bad caliper. I took it off and went to exchange it at autozone for another one. I ended up taking longer than I expected picking it up and I likely let the Master cylinder go dry. I immediately filled the master, put on the new driver side caliper and started bleeding all the calipers. Still have no peddle. While I was bleeding, I wanted to check the passenger side, being that it was also kinda hot the day the driver side got stuck. I jacked it up and tried to spin the wheel, that one was very sticky too. I checked the pins, C clamped the piston in and slapped it back on. I also put on a new brake hose while I was there and prayed that was the problem. Wheel spun but after applying the brakes, it gets kinda stuck. I know the pads make some contact with the rotor, but it seems to me like way too much friction. I can turn the rotor by hand, but it's hard. So now I got no peddle and at least 1 front caliper that seem to be sticking (I'll check the drivers side tomorrow to see if that one still sticks) the way things have gone, I'm assuming it will stick just like before. What else could the problem be? I don't have the money to bring it to a shop and I'm considering selling the car. It's driving me nuts.
