Hey guys, had a weird issues this past weekend that I'm still trying to solve.

I have a 2005 Ram 1500 4x4 SLT with the 4.7. 2 Wheel ABS.

Passenger side caliper pistion went bad so, swaped that out.
When bleeding the brakes broke off the passenger rear banjo bolt so replaced the caliper as it's pistion was leaking as well.

So, Swapped both passenger side calipers. Bled the brakes had a good pedel when pumping but when you turn the truck on, goes to the floor.

Swapped the master thinking it went bad - no luck

Used our scanner to bleed the abs - no luck

Used uv brake fluid let it sit over night - no leaks

Manually bled the abs lines - no air

Every time we bleed the master their is air in the rear. We've tryed two new masters one from Autozone and one from napa both new.

My question is what in the world can we do to get this truck back on the road.

Thanks

 

Sounds like you may still have some trapt air in the ABS motor. I can be a PIA to get it all.

 

No air coming from any lines, no leaks , new master. This is weird we were thinking maybe abs pump?

 

did you re bleed the entire system after bleeding the ABS?
