Both flexible brake lines running from the hull to the axle are plugged up. Both worked fine six months ago.

Have you kicked over any garden gnomes lately?  That's exactly the sort of thing that gnomes would do.

Yup.

Decades of sitting and lack of use aren’t kind.

That doesn't make working brake lines go bad.  Have a line on someone to make em, passed it to M35.  My money is you're using non-Soviet brake fluid.

Good luck finding an alcohol based brake fluid. I have called every manufacture I can think of and they didn't even know that was a thing.

Vegetable oil based.

Castor bean oil, ether, and alcohol blend.  Original brake fluid, and given the current issue, it would explain the issue.

If we get modern brake lines, then the problem goes away for the lines - but it remains for the seals...

Mil5606/aero shell 41 is listed in the manual as an acceptable hydraulic oil.

I got nothin, then, unless the Soviets changed out the brake lines every 6 months?

From wiki, since shell 41 is mineral oil:

The advantage of the Citroën LHM mineral oil based brake fluid is the absence of corrosion. Seals may wear out at high mileages but otherwise these systems have exceptional longevity. It cannot be used as a substitute without changing seals due to incompatibility with the rubber.[15]

I like watching the progress of this. And those wheel cylinders look pretty bad. Nothing a good cleaning and honing won't fix.

And for all of us that own military vehicles, we all know there is nothing really cheap about owning or working on them. My 1962 Willys M170 Ambulance has been sitting for a few years since the M170 specific parts are very hard to find. The seats and fuel tank being two of the hardest to find.

It probably had the wrong fluid in it at one point...the former owner was not very correct with his use of hydraulic, much less brake fluid.

The hardest part so far to find has not been anything special or hard.

It’s been a hydraulic hose.

I’ve gone to 4 different places to get hoses made all 4 weren’t able to make it.

You should be able to use MIL-PRF-5606H.

https://hmvf.co.uk/topic/21564-which-oils/
Hydraulics including brakes: GOST 6794-75 AMG-10

GOST 6794-75 is the spec: https://www.russiangost.com/p-61247-gost-6794-75.aspx

GOST 6794 was replaced by GOST 6794-2017.
The commercial spec is AMG-10.

https://simex-chem.ru/en/products/aviation-oils/amg-10.html

MIL-PRF-5606H is a mineral based hydraulic fluid that has excellent low temperature qualities.
Aeroshell Fluid 41 meets the specifications of a MIL-PRF-5606H.
Aeroshell Fluid 41 also meets the specifications of AMG-10.
Aeroshell Fluid 41 is also classified as NATO H-515 as is AMG-10 and MIL-PRF-5606H.

Remember, a PRF standard is not a MILSPEC.
A PRF is a performance based qualification.
It's the manufacturers responsibility to meet the MILSPEC (or SAE) requirements of a 5606 based hydraulic fluid.
All the manufacturer has to say is that it meets the performance standards, they don't have to prove it.

AeroShell Fluid 41 should be used in systems with synthetic rubber components and must not be used in systems incorporating natural rubber.
Chlorinated solvents should not be used for cleaning hydraulic components which use AeroShell Fluid 41.
The residual solvent contaminates the hydraulic fluid and may lead to corrosion.

http://www.comolube.com/wp-content/uploads/2017/01/FYI-AEROSHELL-HYDRAULIC-FLUIDS.pdf

For the US Military end of things - MIL-PRF-5606J is a mineral (petroleum) based hydraulic fluid with excellent cold weather properties.
It's very flammable. One reason why the US Military went with a MIL-PRF-83282 based synthetic hydraulic fluid.

My guy had these made in the Russian version of auto zone. They had no problems making these hoses that Americans couldn’t.

Now I need a good stock pile.

There's 3 different importers, I think the other guys will be selling theirs. One aimed at LE, one not sure. I don't know what I'll do with the extra one. Maybe mod it out and drop an LS in it, big block, auto, they are pretty forgiving to what you do with them

Older chrysler stuff is pretty good. Plus autozone and oreillys are the places to go for parts now. And it's in greek, which is easier to read.

My insurance agent is going to have a field day with this one.

Sure.  Shell proof?  No.  Armored cars are designed to take small arms fire w/o hull damage, not cannon shells.

ETA:  I'm more afraid of swimming FadedSun's BRDM than taking it into a firefight in the US.  I should probably be more afraid of not being able to stop the thing.
