M35a2C Brake Failure

[dabtl]

OK, I have a friend with a M35a2c, Air Force model, whose brakes suddenly quit. Normally, I would call it a master cylinder failure most likely. But, with these having dual master cylinders, 1) is that still a probable cause and 2) where can I find a rebuild kit or a new master cylinder?

How do you know the MC is bad, and not some other part of the brakes?

MIne is an airforce truck and it doesn't have a dual circuit system.

Oh, the usual suspects, ebay, ted's trucks, od iron, white owl, saturn, etc.

My experience is that when they simply suddenly fail, the MC is most likely the culprit. It does not show any signs of wheel cylinder failure.

I am going to have to look it over, but it will have to stop raining, if ever.

I know Memphis has NOS units, but I bet any decent brake shop can get it rebuilt for cheaper.

I got some new cups for my MC at NAPA. Don't recall the part number but I just took the old ones down there and they matched them up.
