This is another off the when ever you get a Chance to finish up shelf. It represents a Pete Off Hiway conversion owned by PALCO of Scotia, California and was used on the Petrolia Run along the Coast. It is heavily modified for the job of hauling Redwood with a beefed up frame and rear ends and larger bunks. The side plates on the door are reinforces made out of sheet steel which were common on some offers to add protection to the driver. The model has the large bunker tank which I cast in resin for this rig and squared of fenders and extended fuel tanks. Once finished she will trail a Peerless Upgraded trailer for the job intended. The frame has yet to be extended in the rear for the stinger, but all in due time.

Love the water tank for the brakes. A nice touch not often seen. Mike

yeh, I looked all over for the tank on the net and couldn't find one, so I made a master and cast it in resin. Really a simple add on to make.

here is a tank i did several years ago for my Diamond T 950 logger. I cast this in resin, and it too is a very simple shape. Ap40 Attachments:

water cooled brakes? ? cal Yep, the water is gravity fed thru pipes that literally dribble water on the out side of the brake drums. Some were on both the rear of the truck & the trailer, others were just the trailer as the larger trucks had engine (jacobs) brakes & hydraulic retarders in the powershift transmssions. Ap40

Out here we used either the pressurized tank which had an air line running from the compressor to the tank to pressurize it or, we used what we called a jet cool system which was electrical and pumped the water straight from the tank to the jet nozzles which were mounted on the springs of the truck and trailer and aimed at the brake drums.
Some of the earlier units, had the Tank mounted on the top front of the Headache rack and was controlled by a standard cut off valve which was located in the cab beside the seat. When needed the driver merely reached down and turned on the water for cooling the brakes.
When the Jake came into being water cooled brakes all but disappeared from the Pacific north west, except for the offers which still used water up until the later years of logging.
Another thing some might not know is that in the early years of truckin on the Oregon Coast and the Avenue of the Giants in California, otherwise known as Good old Hiway 101, a lot of lumber trucks used water cooled brakes because of the constant twisting and turning and massive hills of the hiway, to cool their brakes. I also know of on trucking unit which hauled nothing but hay and Ag products, which also had their trucks equipped with water cooled brakes and operated East on Hiway 299 and south on Hiway 101. There were a few occasions you could also find a rig haulin equipment on a lowboy equipped with water cooled brakes. When the chip trucks began to invade the Pacific North West, a lot of them were equipped with the Water cooled system also. Brake safety was an early concern in the logging industry.
One Company in Idaho whos name escapes me right now, even experimented with water cooled brakes on a shay locomotive pulling log trains!
A good example of a place where water came in handy was the five mile run down the Crescent City Grape Vine on 101 going north into Crescent City in De Norte County, California. This stretch of road has all the twisting and turning of a roller coaster while going down hill all the time for the full leg of the ride. Harry, but fun, and a place you do not want your brakes to fail!!!!!

We always ran a Williams Valve. It was a module that hung below the dash and had a small air psi guage in it and a small valve like a water tap to turn up or down the air pressure as the water tank was pressurized and normally 5 to 10 pounds or air pressure. The module also had a hand valve that denoted "Truck", Trailer" or "Both" and the driver made the selection. the water then passed from the tank via rubber hoses and were split at the drivers and again at the trailer and ran to the top of each brake drum there by supplying a coolent to the brakes. When hooking up you trailer, you not only hooked the air lines but the water line.
Logging trucks run on much steeper grades than highway rigs and must slow to maneuver switch back turns or hairpins as some may call them and can travel great altitude changes in a short distance. I have hauled from a 22% grade which is rare but a 12 to 16% grade is pretty normal. 6% grade on a highway is pretty normal.
When running water, one always watched the mirrors to see the two tracks of water left on the road from the brake water. If it didn't appear.................. you were in trouble. Mike

Thanks for the stories guys, the company my dad worked for had some trucks that were set up with water. Some really cool history. Dave
