don't you just love it when one guys starts a post and another jumps in and throws another problem in the mix with his truck
gee it can confuse someone really quick
my suggestion is to create your own thread about YOUR problem and not create confusing comments that may throw others off track.

now as for eugene's problem, usually when these trucks start loosing brakefluid and you cannot find the leak its the inching valve on the valve on the transmission. At will have its own dedicated brakeline off the regular brake system.

As for finding this part? like what was said, ANY forklift company can get you one, they are available OEM and aftermarket as well.
