Customer Question

Hi I have a 2006 chevy tahoe z71 with the np8 transfer case. I had someone pull out in front of me and had to hit the brakes pretty hard the truck stopped fine but after letting off of the brakes and reapplying at the next light thenough pedal went to the floor. It has newer brake lines and upon inspection it is leaking heavily from the abs pump under the left side of the truck. Had a few mechanics look at it and everyone is lost. Code c0131 lossd of pressure is the only code. Can these pumps Crack? Is there a dump valve that can be actuated with a snap-on modish? Any help would be awesome. Thanks

sounds like a seal in the pump busted was the pump replaced of just the lines

Yeah I could understand that but how would the fluid get out? I could see how that would leak inside itself but the lines are tight so my thinking is there a dump valve or can they Crack cause noones ever seen one crack before.?.
