replace the caliper? they're not that expensive... I replaced both my front calipers because the bleeder screws sheared off.

I'd say old age or improper or lack of maintenance is the cause. Just replace it with a rebuilt unit from a parts store or rebuild it yourself if you want.

They usually tend to rust on the guidepins or the pistons. When there is enough rust on there, they will eventually freeze up.

You can rebuilt them yourself if you are comforable with tinkering with something as important as the brakes. There are complete rebuilt sets you can get at the dealers.

The simple thing first. Check the sliders. Pull the calipers off, push out the sliders, clean up all the old grease and such on there, put new stuff and see if that fixes the problem. If they are sticking chances are that's all it is preventing it sliding back. It's all mine was when I had that problem. Still have the same calipers 5 years later, god knows how old they were when I got the car. Also check to make sure the front pads still have the 2 springs on them. They look small and unimportant but without them you can experience drag from the wheel(s) without them. Will also cause brake wear issues.

Even if I don't replace the brakes. I like to clean all that stuff up once every year and a half or so just to keep it all working nicely. Helps prevent premature, or uneven, brake wear.

all you need is a wire brush, couple rags, and caliper/brake grease. All you have to do is unbolt the calipers (leaving the brackets in place) and push the sliders out (I use a large pair of channel locks to do it but even a clamp could do it, this is saying they are stuck in place). Basically you should be able to move them around with your fingers. Should also clean up the metal plates where the pads slide on, and add caliper/brake grease to them too.

It's best to do it as soon as it starts happening to avoid it damaging the rotors and pads.

Alright, let me put this in a better way. If your brakes are locking up do the sliders before you end up in a wreck. Even with the rotor and pads being sketchy on the one side it will still be less dangerous if they don't lock up. I've had mine lock up on me, smelt burning brakes. Seen my rotors end up a burnt blackish blue... For your own safety DO IT .

Like I keep saying, it will help until you have the money to replace everything.
