OK so I look it up and I read a few threads on it but none had the same problem i have. The problem is my rear brakes are stuck and for the life of me I cant figure out why the brakes were fine then the front ones started to grind so I replaced them and after that they acted as if they were always on so I removed the shims and the problem got a little better but the brakes seemed like they were still on. so yesterday I was coming home and they were acting up and as I go to pull away from a light the car wouldnt go almost like the ebrake was on but it wasn't so I floored it and it came loose enough to drive at 20mph which I did for about a mile till I got to my house by which time the rear brakes were litterally smoking. so I tried to replace them today and the caliper was siezed on I had to pry it off with a pry bar to get it off even after I opened the bleeder. so I tried bleeding it to loosen it up but no good and the piston would only go down about half way before it wouldn't go any farther (I am talking about the rear brakes) and I dont know what to do. I looked and rear calipers are expensive so ya what do you guys think any help would be greatly appreciated please help.

Grease your caliper pins, and make sure your e-brake is adjusted correctly.

You need new calipers, cars are an expensive habit

Probably not the e-brake then, they don't tighten themselves. :P

Take your wheel off and take your caliper off, then half off the caliper off of the slide pins.

Basically, grab the left side and right side of the caliper and pull it apart, it should slide off the pins quite easily.

If it doesn't, your sliding pins might be rusted and seized, clean em up and grease them well and see if that helps.

You won't have to replace the calipers, I just rebuilt one of my rear calipers the other day and replaced all it's rubber bushings and greased the pin.Fairly easy.I might do a write up once it stops raining and I have time to rebuild my other side.
