Hi. New here and need some help.

Changed out front calipers and hoses. When I went to bleed, sprung a leak in the rusted line to the rear. Replaced that. I've bled the brakes in the proper sequence (RR,LR,LF,RF) several times both engine off and engine running. (Open bleeder, push pedal, close bleeder).

Have pedal when off, basically none when running. I'm stumped. I see things in the archives about needing a scan tool to bleed out the ABS with similar issues but nothing to indicate that solved the problem.

I really don't want to have it towed to the dealer if there are any other options.

Sounds like the master cylinder ran dry and you now have air in the MC. It will need to be bled separately to get the air out. This is typically done on a bench with small jumper lines directing fluid back into the reservoir, but can be done with the MC in the truck.

 

I had the same problem and had to bleed out the abs unit.I was lucky enought to have a friend with the proper scan tool that could do it.

 

Gravity bled the brakes a couple times, all seems to be working now.
