Leaking rear caliper- what can cause this?
Earlier this week I had pulled and rebuilt my right side rear brake caliper on my '84 T/A. As far as I was able to tell it had the recall upgrade on it. But it recently had been seeping fluid past the piston, and since it was about 5 years old I figured the seals had worn out. Pulled the caliper apart and found it to be pretty clean inside- replaced all the rubber components from the rebuild kit and put it back on. Bled the brakes and stood on them to make sure no leaks were present and didn't find any.
A few days later- and having driven it around a bit in that time(about 10-15 miles since the caliper rebuild) - I was getting ready to replace the bushings on the rear sway bar when I noticed that once again the caliper had started leaking again
What could be causing this? The driver's side caliper is working fine- no leaks at all and it was replaced at the same time the right one was. Since I replaced the seals the only thing I can think of is that the piston is defective. Is this possible?

I'd check a little closer to see exactly where it's leaking from. It may be leaking around the e-brake lever and your piston may be fine.

I guess I'd get the car jacked up and the wheel off, and have someone step on the brake while you take a look around to find the leak.
