I have a 96' 3500 had the front pads replaced rotors turned new rubber lines to the calipers new master brake installed. They (mechanics) told me that the ABS dump valve is bad . (they told me this when I picked it up last week . Problem was not there prior to the master brake cylinder install) I read on an older post that the ABS dump valve also has to be bled . I called them today and they said they would start from cratch with another new MBC and bleeding the dump valve . In the meantime I have to find a source for a ABS dump valve,as they contacted both Dodge dealers and they both told them that they no longer make those ABS dump-valves as well as Pepboys and O'Rieleys ect. . So my real question is where to find a new ABS dump valve for my 96' 3500 ? I have a brake pedal that stops O. K. at an easy stop,but if you press it hard the pedal goes all the way to the floor ! In a hard brake it goes all the way to the floor . Yes it will stop the truck but when ? So far it has not been too late of a stop ! That is the reason it is now back at the shop . If any one can help me in finding a source for theABS dump valve I would be thankful . John
