need help!! cant bleed brakes?

[99ranger4x4]

hey guys just swapped the new rear end in, swapped my backing plates and brakes onto it from my old axle. now all lines are hooked up and i got to bleed them and i cant crack the nut? i mean the nut on the nipple. both sides are frozen solid. hit it with some pb blaster and it didnt flinch. i put a socket on them to try and get some leverage and it didnt do anything? i need the truck to get to school tommorow. comon guys bail me out here

gravity bleed over night....
raise front end of truck, open master cylinder, fill with brake fluid. all the air in the system will go up to the highest point of the brake system (wich is now the master cyl.)
should be good in the morning.

Sounds like you're dealing with simply a case of seized bleeder screws here, right?

About all I know that you can try "in a hurry" is putting a 6-point box-end wrench on them, and LIGHTLY tapping it with hammer to break them loose. A lot of light taps is better than a couple of good whacks . . .

If you had more time, the PB Blaster would have a better chance of soaking in.

Good luck!
