Max IV project

Marc. You where a little quiet for a while. I've been wondering what you have been up to. This explains it. Hello R.I. you out there? This is a REAL brake system. Take some notes.

VERY interesting. Looks more installer/repairer friendly than the T-20 output shaft mtd.discs that I'm currently working(fighting) with. Thank you for sharing this Marc.

Nice work Mark. I've been considering a middle skid plate as well as Argo type laterals. I'd not though of moving them with a Hustler type mount good thinking. I especially like the split collar and argo flange conversion

This is a REAL brake system. Take some notes.

Minus the hydraulic calipers, this IS an RI brake system. RI had this setup (with mechanical spot calipers) on the original RIMs and Max IVs. They did a great job of breaking, but they needed an aweful lot of refining. I bet Jersey has already accomplished most of the necessary updates, though.

On my RIM, they are basically a brake disc on a shaft with no bearing; only a bushing. They floated side to side quite a bit, and were only held "straight" by the caliper. And, boy do they really spin! RI did have a good set up, but looks to be done as easy as possible. With the addition of hydraulic calipers, and if you can put an insert bearing into each disc and C-clip it in place, it'd be tons better than the orignal design.

Mike you are correct, this is the early max setup with the mechanical units attached to the frame rails. A little Busco mud and the mechanical brakes were frozen and impossible to get to. Changing pads will be a 5 min job now. I used a non floating caliper with 2 pistons to center on the disc and should hold the disc centered. Originally the bushings just rode on the shaft. No grease port or way to lube them. I cross drilled the shaft and added a Zerk. I still have the bushing setup but replaced the sleeve bushing for a shoulder bushing. If the bushing does not hold up Ill machine the sprockets for ball bearings. The hand brake has a parking brake feature also. I did look at moving the trans forward but the brake sprockets on the center axles are the wrong spacing to make it an easy swap.

Looking great Mark!
