I'm looking at buying a truck for a friend. It's a '63 IH Loadstar 1890. Thing is, it's been sitting for over 10 years, and doesn't run. How's a guy supposed to move the truck without air pressure to release the brakes? Would he have to pressurize the system from another source? Any ideas are appreciated. Thanks a million.

A 63 model should not have cage brakes just back off the adjusters all you need is a portable air compresser to charge system to release them .

I have moved many a truck with air brakes just tighten up on the big nut on top of the canister to release the spring brakes. Be sure that you have the vehicle blocked or hooked to tow vehicle first.
Walt PS don't forget to back them off after moving it.

If you have to ask. Just pay someone that knows what they are doing. It will be cheaper and faster in the long run.

Check the rear axel, and see if you have air brake canisters. It was possible to get hydraulic OR air brakes for the 1800 series Paystars. If the saucer shaped canisters are pointing towards the wheels, these are wedge brakes, and could be frozen in place. Maxi brakes were not that common on this small of a truck back then, and your emergency brake was a drive shaft breke drum by the transmission "U' joint. This is a good place to look, if it was sitting for ten years, could be rusted in "park position". IF there are maxi brakes, check to see if the emergency side of the can (pointing AWAY from the axle, with NO air lines to it, but has a hole in the center)is rusted with any CHUNKS of rust comming off. DO NOT MESS WITH IT, if you've had no experiance with truck air brake systems. If you are not sure, find someone who is. Know what you're looking at before you tackle it.

In-to-deep,
How far do you plan to move this truck? If more than just across the yard to get it into the shop, call a "Draggin-Wagon"(wrecker). Easier, safer, & cheaper in the long run than any other method.
If just across the yard to the shop you have several choices:
1-try charging the tank to see if everything works. chances are that valves, hoses, & diaphrams will be rotted & leaking, & the shoes will be rusted to drums, so won't release anyway.
2-have a large forklift or loader available? pick up the rear end & push into the shop.
3-hook on with a stout chain & drag it. tires need replacing anyway, so can't hurt anything except make black streaks on paved yard or grooves in dirt.
Be Safe

Just be sure the wheels are well chocked before you go crawling around underneath it trying to release the brakes!

I could be wrong ? or it could of been changed over ,but on one that old I don't think they lock when the air is gone. That old stuff usually has a drive shaft brake that is a hand lever. The others are describing the maxi brakes on newer stuff that has a spring to apply the parking brake when the air is gone. These you have to use a draw bolt and release them.

I believe there is a bolt that is made to go into the center of the brake cans that can be tightened to release the brake.One for each wheel.Hope this helps

on the air cans look for a t- bolt mounted on the can. should be a 1/2 inch bolt. the T end will fit in a hole in can. turn it 1/4 turn than tighten down nut. this will release the spring brake. if you can't find bolts go to truck shop and ask they will know what to do.

Go to each can and tighten down the screw (bolt). It pulls the brakes off.

The spring brakes are easy enough to release If the release bolts are there but then there's NO brakes to stop the truck while towing it... THAT's the tough part!

That sounds like a plan, just what I was lookin' for. We can only hope that the bolts are accessible and they aren't stuck nice and tight.

Yeah I'm kinda worried about that too. I'll start worrying more if I end up getting it. Thanks for the reply.

Theres a special tool made just for releaseing the brakes for just that reason. On a 1963 if may or may not have spring parking brakes. My 1963 Diamond-T has them but an IH might not. Any how you can get that tool at any good truck stop. DON'T even think about trying to open up one of those pods if it has the spring type parking brake it can and will take off body parts if you do so. The easy way to work the tool is to get air in the system if you can then install the tool that way theres a lot less work to get them to release. BTDT more then once when I was still trucking cross country. I've still got one of them tools laying around here some where. Looks sort of like a bolt but its not a bolt and is much stronger then a common bolt is
