Making another thread just to make them easier to search for in the future. I dug into my right steering brake issue today. Removed the floor and got that spring out which I thought was the issue. That of course didn't fix my problem since nothing is ever simple for me. Photo attached of the spring they had in there before compared to the proper part.

Now that it is in i can push the brake in a bit easier but it still won't return. Im sure they had the huge spring in there to alleviate that issue before but now fails. The pedal does depress about 3/4 of the way as the manual states (same distance as the other) so i do not think i need to adjust number 2 adjusting nut in the second photo. I believe number 9 support screw needs backed out a turn and a half but i cant seem to find it. Neither the servicemens reference book nor operating manual are clear as to where it is.

I'm also considering that isn't even the problem and it may be the length on rod 3 but trying to turn that bolt was not going well so i shut it down for the night and figured id ask the experts once again. Appreciate any input you guys put forth.

Hi, BVAL.
Unless I am much mistaken, the support screw, 9, is under the steering clutch/brake housing and is accessed from under the machine. That being the case, there is always the possibility that some previous encounter with Mother Earth has broken it off.

Just my 0.02.

I guess that is possible, I did open that housing and looked but did not see it. I'll check again later today while I continue cleaning all the built up dirt crud out from under the floor area. The more I think about it though it doesn't seem like that would prevent spring back just difficulty pushing in but I've only messed with standard drum/disk brakes on vehicles.

Grabbed my service manual and see what you are talking about. Did not think I would need to mess with the steering clutch unless I needed to replace drums.

Number 2 is the brake adjustment. The support screw is under the tractor sticking out of the case, has small curved piece welded to case to protect the screw and lock nut. The steering clutch adjustment is no shown in diagram posted. It is a large nut(I want to say 1 5/8 inch head but large none the less) with cone shape on the bottom with a lock nut. DO NOT ADJUST THE DIFFERENT ROD GOING INTO THE BOOSTER until you have the other things correct. And most likely you never adjust those unless the uneducated have already been there.

Attaching another photo so it is shown but it would seem the uneducated has already been in here and now another uneducated (me) has to sort it out. I have seen the steering clutch adjustment bolt but I left it be because the service manual made no mention of adjusting the steering clutch for brake adjustments unless the drum needed replaced.

Just to clarify, the brake does work when depressed, it was just very difficult to depress and didnt return. With the new spring it goes in easier, but not close to as smooth as the left side and still doesn't return. The pedal depresses the proper length so I did not adjust the brake adjustment bolt. Just seems like something is hanging up the rod. After work I'll get back at it and continue cleaning down there and check that the bottom screw is turned out 1 1/2 as it should be.
