Did you flare your brake lines or are they factory flares?
Did you double flare them?
Did you tighten each connection, then back it off and retighten it again...doing this 3-4 times and you'll see the wrench make the fitting a little tighter each time using the same amount of force. This process helps seat the flare...
I personally wouldn't run a brake line over the drive shaft. If a U-joint ever breaks the shaft will beat the heck out of everything in it's path...I'd hate to have it smash a brake line and loose my brakes at the same time.
