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!

 

If they will screw in individually, then the threads and fittings are proper. Most likely an alignment problem. Once one side is in, you may need to flex the tubing somewhat to get the other side to line-up straight in order for the threads to engage properly..

 

thanks i bent the line some and went in smoothly but now when i go to bleed brakes not getting any fluid coming out the bleeder screw all lines are in good and not leaking i also cleaned the bleeder screw

 

Not sure what valve this is "...i also cleaned the valve out."

I had a similar problem when I had more than one bleeder open once. You want to close all but one so there's no suck-back when you release the pedal. You'll also want to close the bleeder before the other guy releases the pedal. Then open it after he pushes it to the floor. Normal bleed procedure, in other words.

I've heard of some people using gravity to fill the lines, but that didn't work the one time I tried it. Doing a normal bleed procedure worked better for me.

 

bleeder screw not valve my bad also all are closed and i tried bleeding normal like you said above still no fluid coming out going to try some more troubleshooting tomorrow

 

Another option is to hook up one of those hand vacuum pumps and see what you can pull through. Similar to this one ... https://www.harborfreight.com/automo...kit-63391.html

Did you do anything with the main cylinder? If it went empty you'll need to bleed it properly before doing the lines. "Bench bleed" they call it. You can get a kit like this one - https://www.autozone.com/brakes-and-traction-control/brake-master-cylinder-bleeding-tool/p/dorman-help-brake-master-cylinder-bleeding-tool-14151/1104881_0_0?spps.s=&cmpid=LIA:US:EN:AD:NL:1000000: GEN:22350391884&gad_source=1&gad_campaignid=223567 57832&gbraid=0AAAAADkcoVvkVVHKKlQzgBVMgi6keeky6&gc lid=EAIaIQobChMIlZzVwpuFjgMVBYjuAR3WrQgkEAQYAiABEg K0fvD_BwE&gclsrc=aw.d, or make your own out of some fittings and hose.
