Brakes locked up

G Guest
My car has about 60 miles on it since I put it back together. Today while driving it I could feel some serious drag, I got it home and jacked 3 of the wheels up, I could turn them only barely. The rear brake lights were also on. I let it sit for 1/2 an hour and they were still tight. I took the master cylinder off the power booster and the plunger was where it should be. I bolted it back together and it seems to be fine. Any idea what else I should look at?

I don't know if it's the same problem or not but I had a similar situation a couple years ago. After my car had been apart for a year, on my first test drive, after having carefully set the plunger rod in the booster and bleed my brakes, they began to tighten up. I was only a couple miles from home, but by the time I got home it was like driving with the e-brake on. Heated the rotors up pretty good. I talked with a couple of people and found out it's actually a fairly common occurance. The diaphram in the booster can relax a little and take a slight set. After it's exercised a little, it becomes a little more pliable and has a different unbiased position. After I backed off the plunger rod, I haven't had the problem since and the brakes have been rock solid.

Good luck,
Kelly
