The truck is drivable but barly. I had a hole in one of my brake lines wich i fit tonight when i got home. It wont seem to hold pressure now. If i pump the brakes twice it holds enough pressure to stop but the front brakes only work. If i pump the brakes to much the peddle goes rock hard and it takes all my power to stop the truck. I bled the brakes and cycled a big bottle of fluid throw it and the peddle still creaps to the floor until the ABS and (P) e-brake light comes on. Should i take it to a shop and have the full system bled on the machine or is it some thing else. The problem only started when it started leeking brake fluid one the rear line.

Booster?
Master cyl ?

any advice will help
Thanks

 

definately sounds like air, and that can be difficult to bleed out when it has to go through the accumulators/valve etc in the abs system. i have also seen when you lose a particular brake or line it causes the proportioning valve to shift, then if a pocket of air gets in the valve it may not want to reset itself it and that valve has a button on the end you can press and maybe help.

 

i broke off the bleeeder valve on the rear drives side so i couldnt do a proper bleed, im thinking its the problem

 

Bleed it some more and make sure your rear brakes are adjusted correctly. If you replace the rear wheel cylinders upgrade to the Chevy 1-ton cylinders. You'll stop a ton better.

 

part number by chance?
