Brake bleeding

[REVNORR82]

I have a 07 classic Silverado. I just replaced the rear line from the absence to the axle. Now no matter what I try I cannot get it to get any fluid to the back brakes I'm about to loose my mind some one help.

open both bleeders and let gravity bleed.

Mityvac is the easiest method but the above should work as well. Pump and bleed isn't working?

I had a buddy do all his brakes and he couldn’t get fluid out the back because he put that line in the wrong hole on the ABS block.

Is your buddy D.J. Lubel?

So if you have one of the 2000-07 trucks and you run the master cylinder out of fluid the abs for what ever reason will not let fluid to the rear (I'm assuming this because I blew my rear brake line) but the only way I could get fluid to the back is to push the fluid from the reservoir using some home made things to put pressure on the system then bleeding.

That's normal. When you start with a dry master there is a procedure to "bench bleed" it before attaching the lines. Glad you got it fixed.
