rear brake line blew from rust hole i have new metal rear lines but cant get the lines to screw in i can screw in one side at a time. (both sides smoothly screw in but after I screw in one side the other wont properly thread ) Any tips suggestions THANKS!

 

sounds like the line is either too short or not quite bent right. flare nuts have to be dead on for them to start

 

So i got hard lines on just had to bend the line some and it screwed in smoothly but when i go to bleed brakes no fluid is coming out of rear right vent screw

 

probably clogged with dirt

 

so i removed valve cleaned out till i can blow air through and pick, then screwed back in. Started up truck cracked the bleeder screw open still no fluid. Lines are tight and no leaking. Do i also clean the hole the bleeder screw goes into any help on next steps? THANKS AGAIN!

 

Have to reset the equ. valve, plus, on some ABS boxes there is an inlet screen that can get full of rust and junk that needs to be cleaned.

 

We don't know (for sure just what you are doing ?? go back to the junction where you screwed in the two lines.. From what you say you have fluid coming out one side.(am I right??))
Loosen the other side @ that junction....& bleed it there...You should have fluid right away I would think !!
When you get fluid coming out retighten it & go to the wheel & bleed it there.
If no fluid comes out @ either point you bleed you must have a restriction there.(1st the jct. then the line out to the wheel & then caliper or wheel cylinder etc. ) ..
Replace where you have no fluid be it @ the jct. first then the line caliper etc.
