My 170K car has new OE brakes lines in the rear last year (put on by me)...the left side was leaking fluid from what I thought was the tired old original rubber line(a few drops overnite)...still leaks; apparently only when its warm. I can't tell where its coming from.

I'm thinking a bad caliper(internal seals?)...anyone else ever have had this problem? Its a daily driver in every concievable condition...snow, mud, sand, shallow streams etc.

Yes, the new line is tight and not leaking. My first thought myself. Any ideas before I take the wheel off and tear it all apart? Thanks guys.

Mine started to leak after I bled the brake fluid. It turned out the bleeder screw stripped the thread inside the caliper. Whoever did the bleeding in the past(dealer I assume) screwed it on wrongly but it held until I took it out. I wanted to loosen it and once I turned it 2/3 of a full turn it popped out... And after bleeding I wanted to screw it back and it would just keep spinning...
I wound up getting a new caliper and the leak stopped...

Hey now, thanks for the input. I didn't even consider that...I did bleed out the fluid to new Ate Super Blue not long before I did the lines...

I will pull the wheel and check it out.
