While I havent got any photos on my 38 1/2 ton that rod rides in a hole in the middle of the frame cross member (2nd from rear) at the front of the rear spring mounts. There is a plate that 2 wheels bolt to so the cable can change direction. If you require photos let me know as I dont have the deck in place.

This is out of the 38 manual. Don't know if it'll help or not.

I have the same question as the original poster.

I have a 1941-46 chassis and am hoping to find an illustration of the parking brake system. I have the master parts catalog and a 1940 shop manual (the project I purchased turned out to be a '40 cab on a '41-'46 chassis) and neither has a picture of the parts involved aft of the parking brake handle.

Here are some photos of the parking brake assemblies on my ‘37 and ‘46.  They are basically the same design from one year to the other.

The bare frame photos are the ‘46 and the other is the ‘37.

Thanks Lee!

That assisted me very much. I hope that it helped Cochinapatina36 as well.

In case needed, I recall hearing some guys reporting, they found pulleys at a hardware store in the garage door parts section.

Two things:

Why are there TWO holes in the crossmember of the frame where it is my impression that the emergency brake rod passes through. If it only needs one hole, why are there two? Is there a bushing or some other item that would go around the brake rod to keep it from scraping when it is moved?

The second is that there is a Tech Tip on the Stovebolt Forum where the garage door pulleys are suggested. The pair I purchased have ball bearings which are very visible and I wonder how long they will be viable when exposed to road dirt under the bed of the truck. I am still a long ways from putting them to the test.

I can't answer your specific questions but I have a suggestion. I worked in the aviation industry for over 30 years. Nearly all light, medium, light-heavy and older heavy aircraft use manual control surface controls. This involves cables and pulleys. If you have an aircraft salvage yard near you, it might behoove you to pay it a visit. I'd wager aircraft pulleys would be far more durable than garage door hardware.

Thank you very much for posting the pictures! That really helps.

37Blue's photo of his 37 is exactly the same as my 38, I think the 2nd hole is for the variation between LHD and RHD so check alignment in both.
