Got this loader. Brakes didn't come with it. Tongue

Brakes just don't work. Master cylinder was DRY.
Poured brake fluid in but it doesn't even seem to try.

Where do I find info on getting master cylinder parts?
The master cylinder looks simple. Any standard vehicle cross?
Dealer still have parts? AgCo?

A company called minn-par should be able to help you. You can search it on the Web for a phone number, or else I can get for you a little later on. Darrel

Still have done nothing with brakes.
What happens if i put a master cylinder on it and the brakes lock up stiff and won't let go?
Should I spend some hours taking wheels off to check first?

You have to start somewhere, I doubt it is going to heal itself. Best you can do is start with the master cylinder and see if you get brakes. If not you just have to work your way through the system. You may get a brake pedal and find a wheel cylinder leaks, then you repair that one and try again. Or if you decide to pull the wheels to look at them, plan on doing a full do a real brake job as you will have the hard labor of pulling the wheels already in it at that point. Just looking will not tell if a wheel cylinder is going to fail or jam up, unless you can see the piston(s) rusted solid in the bores. Most if not all the parts can be crossed, or matched, to older truck parts. The master cylinder and wheel cylinders generally have casing numbers to help ID them. If yours has the vacuum assisted brakes, you will have other parts to check out and possibly replace.
