1968 Ford F-600 Air Brakes

[FoMoCo1]

I have a 1968 Ford F-600 with a 330 CID 4 speed transmission with the 2 speed rear-end. The truck was originally ordered and owned by TVA (Tennessee Valley Authority). The truck has air brakes, not air over hydraulics, only air brakes with a compressor mounted to the front of the engine.

I'm been searching for a diagram for this system so I can identify and replace parts, (mainly air hoses). But, any other part that may be bad. The truck was parked for over 25 years and I got the engine running however I have no brakes due to rotted rubber air hoses. Has anyone ever seen this system and could offer some help please? Thanks!

Never would've thought about F-600 air brakes on a tractor forum. But, a lot of the old grain farm trucks were F-600's and such. I figured someone here may have one or know about them. Thank you for you're help! Much appreciated!

I have a '62 F700 Grain truck, but it's hydraulic. All the brake info is in the shop manual, it covers all F series up to 800, not just the light ones. I think the 68 manual is the same, however by '71 or so they were split up.

Which shop manual are you referring to, do you have a manual showing strictly air brake systems?

I have the 61 manual, it has a section on air brakes, but I have no scanner, and I expect the brakes changed in 67?

But here's the first part, most of what follows is tractor-trailer brakes.
I had to reduce the size, and quality is compromised, if you want an E mail copy, PM me your info.

That picture is what I have! At least very, very similar. What are they calling that rear valve at the very back of the frame? PM sent, and thank you!

I know hydraulic brakes went to dual reservoir in '67, probably air changed to dual chamber, but I am not sure, I'm just a hobbyist, not an expert.

At the very back is a "Quick release valve", There are no other pictures of it.

I thought that's what it said. But, I was having trouble making it out. PM sent.

I found this in my '67 horde, if needed.

First page has some air brake specs, that's all the brake info it has.
