Passenger Side Brake Caliper Sticking in Cold Weather

What is your question?

I have an 98 Honda Civic EX. Whenever its get below 30 degree out my front passenger brake caliper starts sticking. After driving for a short period of time and my car heats up it stop sticking and everything is fine. Same thing happened a couple months ago. The colder it got the more stuck it got. I ended up replacing the caliper and the brake hose. It seemed to fix it until the other day when i noticed it was starting to stick again. I do have a small leak coming from where me brake hose connects to me caliper. I haven't seem to be able to get it to stop. We have also have had snowy/wet weather recently which has also kept me from being able to fix it.

What makes this problem better or worse?

Colder it is the worst it gets
