I also noticed that on the brake lever where you would insert the fluid, there is always fluid there on a warm day as if it is leaking out.
I had a bike shop bleed them for me but they did it in the spring so there wasn't any issue.

I'm not a bike mechanic but it sounds like your break line is over filled. When the fluid is heated it expands which explains the clamping and the leakage.
