Never tore into the brakes. The JD friction modifier was in a small pint bottle at the parts dept. Just add it to the trans fluid. Did not have chain guards.
Ok - good deal. I will do that when I change all the fluids.
I may have done them some good - I went out and "slam braked" them a couple times. They sounds better already. Maybe they need some cleaning off.
Out at my hunting place there i all kinds of nasty stuff like rocks, etc. I think I will fabricate some plates to go under those chain openings. The rest of the bottom looks pretty well protected.
