Caliper's locking up, Just need to bleed? Options

[senick]

So as the title goes, I had my car on a lift, engine on and in neutral, and the front passenger wheel was encountering a decent amount of resistance when spinning. I can only guess it's the caliper. Interestingly, the passenger rear is experiencing the same problem, only its the shoes against the drum. A guy I worked with suggested it's a bad caliper, which is also causing uneven pressure distribution in the back locking it up as well. I'm just thinking if the caliper itself is bad, or I just need to bleed the brakes and see if there's stuff in there. What do you guys think? And is the procedure for bleeding pretty easy with these cars? The old horse is pretty weather worn, so I'm worried I might snap something off the release valve when I try and bleed it.

I had a few problems like this when I had my celica and I rebuild the caliper and it did nothing, the slider pins were still shiny and i relubricated which did nothing, in the end new pads seemed to fix the problem but that could be due to the fact they were better although I would of thought they'd brake harder but still lock up on one side but it was perfect after!

Before I sold it realized the rear discs had a lip so it could of been that also.

My point here is there is alot of things it could be and its one of those things that you're gonna have to replace alot to get to, I suggest just popping the pistons out and giving them a light sand with LIGHT sand paper and a clean providing your discs aren't warped and your pads are even, I know I had alot of trouble getting rebuild kits here but if you can get them for cheap then start there! its easy.
