[Cecil R Bearden]

Wash them with a couple of cans of Brake Cleaner.   Keep the spray 
downwind...

However, 4 disc brakes to fit my combine will run me $450 from Deere—they are not available aftermarket—it appears the 3300 was the ONLY thing to use this particular transmission. I’ve got plenty of pad left on them. I had a light leak/sweat on one side, the other is dry. Anyone ever had any luck degreasing a set? As stated they weren’t really greasy, but they just have a look and feel that to me suggests at some point they have gotten grease on them. I’m thinking about soaking them in Purple power for a couple days. I washed them off with Gunk yesterday.

Installed new balls and springs. This time I am going to try re-machining the 2 steel pcs that actuate the brakes as I can tell they are not wearing flat. I’ll hand sand the discs on a ground plate or surface plate—yes I know they are probably asbestos so I’ll take reasonable precautions. I’m also going to replace the seals in the transmission.
