Need Help with Brakes ASAP

[ClassicRedneck05]

ok so i have my 72 and when i was driving the rubber brake line on my front right side going to my caliper burst and i lost my brakes. well i was able to stop down shifting and using the E-brake a little well i replaced the line and the little bleeder valves are so tight on the caliper i cant get them loose to bleed my lines well i was told to losen the line where the rubber hose goes into the brake line and i was actually able to get it to come out there but i still have no brakes i can pump it about 5 times and it will get harder and hold but still goes to the floor any ideas? i really need to get this fixed

also while im on the brake system i have never been able to get any fluid to go to my rear brakes any ideas on that would help to
