Brake lines coming loose?!
A few months ago I replaced the brake lines on my '69 with all new stainless steel lines.
I installed all the lines, tightened them and then pressure tested the entire system. I retightened any small leaks and then filled the system with brake fluid and bled the system.
I'm now getting ready to get the car on the road this spring and I notice that the rear compartment of the MC is losing fluid. I trace it out and I find that the 2 trailing arm lines are leaking, very slightly, where they connect to the calipers.
I retighten the lines and refill the MC, then a couple of days later the same thing is happening! So I retighten them again and refil, then a few days later, same thing!
Could this be a problem with the new lines or with the calipers? Or is this normal with stainless lines?
Any one have a similar experience?
TIA
Dave

some times you need to reseat the SS fitting several times since they are so hard, i would try this at least. perhaps they are not tightening down all the way and you are getting a false impression that they are seating .....i would alternate between tightening and loosening them and see if they snug up better
