85 trans am brake problem

I just picked up a 85 trans am. I am the second owner and the car has been in storage for 12 years, but driven in a yard 4 years ago. My problem is I took the car for a drive down my street and noticed when the brakes where pressed it pulled hard to the drivers side. I removed the rear wheels and used an air compressor to blow the crap out of the brake assembly, the brakes where in near perfect condition. Reinstalled the drum and tires and moved on to the front. Both driver and passenger pads looked great, but when i tried to remove the passenger caliper it was stuck. I broke a c-clamp trying to remove it, I replaced the caliper after I got it removed and when trying to bleed the caliper my brother said he couldnt even move the brake pedal. So I climb in the seat and sure enough the pedal wouldnt move. I started the car to see if the power brakes would allow the pedal to be pressed and it did after I held it for like 1 min, but when i let the pedal back up it again was stuck up. So my ?? is what could have changed the pedal not pressing. It worked before the work i explained above. The drivers side caliper was alittle hard to compress to remove but it came off. Any info anyone has would be nice... Thanks

You may have to replace the brake hose on that side. They break down on the inside and hold pressure. When you compressed the old caliper it pushed pressure towards the master and the hose is holding it. Do you get fluid when trying to bleed it? Does the pedal go down when you open the bleeder on the other side? If it needs to be replaced, I would replace both front ones.

Agreed, I think your problem is in that brake line. The car did sit for a while and some corrosion probably built up in there and when you pushed the fluid/crap back through the line, it stuck in there more than likely. Replacing that rubber line from the hard tubing to the caliper should do the trick.

that car has been sitting a LONG time and you need to just drain and flush every thing in that car that is liquid.

thanks for the help. It was the hoses going to the calipers. I had already replaced the passenger side caliper as you know, but i didnt have to. I removed the hose to the drivers side caliper which was also very hard to compress and after removing the hose it went down without a problem. Replaced both calipers with new one since i already brought one. drained all the brake fluid out and replaced with new, blead the system and now she stops like shes new again. thanks all for the help and now i know where to go if i have a problem.
