I take it then there was some kind of pump and tank to spray water on the drums when going down hill?Cooler.
That's a pretty elaborate set up.
On most Off Highway and some Highway Logging Trucks there is a water tank behind the cab . The water is to spray water on the brake drums ( that little 3/8 pipe amid at the brake drum in above photo ) . After the water tank is filled and the cap on top of the water tank is secure , there is a little shut off valve on an air line , that when open sends air to the water tank . As the trailer of a logging truck going down hill is higher than the water tank on the truck , about 10 pounds air is used to push the water to the trailer brake drums. ( when one parks the truck at the end of a shift with a full water tank , that valve must be closed as if air bleeds off during night water will be pushed back through air system ) The water travels from the water tank , up through floor in center pipe with yellow handled dump valve . When the yellow handle is lifted up water flows through the front pipe with a tap valve going down through the floor to the Truck rear brakes and water travels through the back pipe with a tape valve going down through the floor to the Trailer brakes . The water valves are to control the amount of water flowing to the brake drums . After reaching the bottom of the hill the dump valve is closed . When stopping the truck at Dryland sort or shop the water is cleared out of water lines using a blast of air with the brass "Tee" with a black button facing forward on top of pipe .
