On my 46 H the right brake chatters badly when using to slow the tractor on a hill. Left brake is fine. The brake hold well and seems to be adjusted well. I dont use the tractor all that much so it has not bothered me but I have a little time now so I took off the drum and it all looks OK. Still has plenty of linning left. Going slow, no problem. Just chatters bad on hills or when used to slow tractor. What should I be looking for?

In addition to what others have posted a tiny amount of oil on the lining can also cause the brakes to grab and yet hold very well. Check the seal for weeping oil.

I agree with Owen, to check it, look for color differences and glazing of the friction surface.
Limited use can also glaze the brake when surface rust is embedded into the lining.
If oily, use brake Kleen spray (off of the tractor) to soak the lining. then let it dry for several hours. If nothing was removed (no discolored oily residue in the spray wash) I would roughen the band and drum with 250 grit silicon carbide paper and put it together.
If there is oil, be sure to let the brake Kleen solvent dry completely then use a propane hand torch to heat the lining (off the tractor). do not let it catch completely on fire, just warm and burn sections at a time to boil off the oil/grease. Check the bull pinion shaft seal to assure no oil leaks on to the band. Jim

Also make sure there isn't any play in anything (like the hole in the trans case wollered out). If the brake shoes can move side to side in response to the pressure they will be working cockeyed. That can bind them and cause them to chatter.
Some years back I rebuilt a Farmall A and the brake linings were completely soaked in transmission grease. At that time I had a book that said I should burn them with a torch. I did that and they burned completely clean. The problem is that the brakes are very sensitive such that if you step on the brakes with any force at all the wheels lock up. It is kind of like having power brakes, but is actually too sensitive. Something must have burned out of the linings that they operate that way as I have a Farmall B with new brake linings and they work normal. Thought I would ask if anyone has any explanation for this.
