oil gasket leak (STILL!) plus no brakes HELP

[Posted]

Guys I installed a new motor, and used a one piece blue gasket, chrome pan. It leaks around the crank chevy 350. I drained it dropped it 3/8 o an inch or so. All I have. I used the black rt around the front. Still leaking! Do I drain clean and repeat? Better choice of rtv? Also I have drum brakes all way around. Bled twice but still low to the floor and not stopping well. New master cylinder and vacuum pump. Something pulling air? How do I test? I need help please!
