Tore up brake disks-actuator assembly, etc.

Merry Christmas y'all,
First, I want to thank all of you that have helped me, it is greatly appreciated and every comment adds to my knowledge and perspective.

As I have been going through my 73' 4000 I have been surprised at the lack of wear, corrosion, etc., even with some moisture in different areas. The PTO clutch plates looked good. I started to get into the LH axle trumpet and the first disk, looked great and I expected that assembly to look good, certainly serviceable. That is not what I found at all. It looks bad, severe wear, and the wear is not where it is supposed to be. The pressure plate, the actuating disks are grooved a good bit. I thought about OEM quality parts and thought that Messick's would be the place. I would be looking at well over a grand, perhaps way more. It was difficult to sort through what they were listing.

I can get the disks, the intermediate plate, but the backing plates, can I get them milled? Other than letting them be and hoping for the best with new disks, replacement the only option?

Apologies for the longish post,
Thank you all very much,
George

Apologies for the double intermediate disk picture.....
I have not yet got into the RH trumpet. I have no reason to expect a different outcome and they probably are just as bad. Will be interesting to see though.

Me again,
Thinking this over, I had a chronic leaking PTO shaft seal and frequently low hydraulic oil. Couple this with some weak brake pedal return springs and the brakes must have always been on, to some degree, causing heat build-up, warp-age and extreme wear. So, a warning to all with these great tractors, keep the hydraulic fluid topped up, fresh, clean and look over those pedal return springs and replace at any sign of them being tired.....

That fits right in with what I tell my customers all the time. Pay me now or pay me a lot
more later. If you fix little problems, they don't turn into bigger ones later.
 

In-line with the Universe's grand plan, any postulation on my part must be proven wrong. In this case, I am better off, so I am good with it. The RH side brake assembly is in reasonably good shape with none of the heat-induced warp-age seen on the LH side. There are slight grooves in the backing plates, but the disks are all looking good and, I think, reusable. Left brake pedal spring must have been weak.
