I gave all my existing brake lines and fittings to the shop.  All that came 
back screwed on fine and tightened up okay.  I am fairly confident that the 
proper fittings are on my lines.  I did go fairly tight but just used common 
sense when tightening.  Did not want to go to far.   I have stripped and 
snapped off my share of regular bolts.  I did not want to do that here.  I 
did find that I could reposition some joints to stop the leaks some time 
back.  I am surprised that this process is so finicky.  I could not get a 
good look at the nipple type seats in the brake proportioning valve.  To 
dark to get a good view.  Thought about stuffing some of my kid's playdough 
in there to get an impression but don't want to have to clean out that mess. 
I watched one of those chop/cut/rebuild shows recently and saw the guy 
putting some "goop" on the copper crush washers that make up the connector 
at those brass block connectors.   What did he use and why?  Are the new 
crush washers hard to seat?  Larry.
