Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
The inspection checklist for sending truck to fires now says " All vehicles 36,000 GVWR or greater shall be installed with an operator-controlled auxiliary braking system in addition to the service brakes (i.e., engine retarder,transmission retarder, driveline retarder, or exhaust retarder " so guess my Question is can I add one of theses to this truck?
Then you need to install a standard tractor parking valve so you can use your emergency brake without it locking the spring brakes up.The truck already has air powered wedge brakes at six wheels, so the E-Brake at the T-case should be considered an auxiliary brake .
I have 2 6x6 tenders and they have never questioned this on mine, one is a Deuce and the other a M931A2, assuming yours is the same ...
My guys are asking if you have any pictures of this if you have already done this.All A2 trucks have the mounting location for a push pull parking brake valve to be installed. The hole in the bracket that goes from the shifter to the dash board. Enlarge it. T your supply for the valve off of your spring brake override supply. This still is a spring brake tank air supply.
Plug the supply port off behind the drivers step and connect a union the spring supply and run it to the parking valve.
Cost is around $75 for everything.
Your truck already has the trailer valve to the left of the shifter. can add the parking valve in that hole in front of the shifter. You can get supply air either a T into the spring brake override or run it from under the truck. Doesnt matter.My guys are asking if you have any pictures of this if you have already done this.
Thanks Gene
