Brake fluid leaks

70 GMC C2500 drums on all 4

All new parts/pre bent lines/etc with the exception of the distribution block, any in line tees. These were inspected, cleaned, blown thru w/compressed air.

Bench bled master w/o issue.

Started to gravity bleed hard lines.

I have a small drip, 1 every 10 or so minutes at the master front connection. Yes, I have flare wrenches. I have tightened as much as I dare w/o stripping it. Still leaks.

The 1st inline tee leaks as well. Tightened here as well. Better but still a leak. Ran outta patience, called it a day(grin).

Questions...

1 - Isn't the front master reservoir for the front brakes?

2 - I searched this site. Does loosening and retighten work?

3 - I am 99.9% sure I have no crossed threads. If I did, wouldn't it leak more than what Im seeing?

4 - I would tend to think, no teflon tape/pipe dope should be used due to the flared fittings.

This aint my 1st total brake job. Don't recall these issues in the past.

Thanks for your time...Don.
