... for Crenwelge (or anyone)...
The operation of my parking brake valve seems reversed (push it in to release the spring brakes, pull it out to apply). I removed the valve and the two airlines and even made sure (by running the truck) that the supply line was attached to the "in" port and the non-pressurized line was connected to the "out" port. I did reverse them to see if that made any difference and it just dumps the pressure out the relief port that way.
Do I have a bad valve (it's a SealCo, BTW) or what? It's actually been this way since I've owned the truck. Everything works okay, just backwards. I am trying to correct all the little issues on the truck before the big trip to Kansas City.
Thanks,
John
