9020 Brakes

Recommended Posts

Buttercup

Recently picked up a 1975 Simplicity 9020 Duramax.

The brakes do not work. I adjusted to 1.25" free pedal travel as per owners manual. NG. Looks like operating lever at Transmission does not activate brakes at all.

Anyone done brake job on this tractor? Looks pretty complex. What are the wear points and what parts are normally needed to get brakes operating?

Would greatly appreciate some advice..

I think you mean Powermax (though a diesel one would be great :D).

Anyhow, I don't have one but have read a lot about 'em. I think it's likely the drop housings in the rear have seals that have failed thus you have fluid on the brake linings. I think you have to fix the leak issues and bake the linings to get the oil out.

Someone will be along shortly I'm sure with better and more info. Pics?

Try a search under the "search" dropdown, then "search the forums" for brakes topics. The brakes are basically the same set up for the 616, 620, 720, Powermax, 4040, 4041

Because of the leak issues I think many of us with one of these machines (or at least me)don't use the brakes much, they just use the hydro reverse and don't go too fast. I remember there have been postings on how to clean up the brake shoes, replacing the bearings etc. Do you have a repair manual or at least a parts diagram to show how they go together?

Well I have 3 powermax tractors and all of them have problems with the brakes or at least they had problems. I have went through 2 now and they have the same problem.The seals at the transmission are leaking. You have to take off the drop axels to get to the seal which is behind the breaks.I have baked the disks and the metal parts along with break clean to get some of the oil out.They work better but not great.You will need a manual to know what to take apart and how to get it back together. Figure about 2 to 3 hours to do each side but the more you do the faster you get at fixing them. Good luck.Bob
