522XI BRAKE RETURN SPRING

[HorseFixer 2,013]

When I got the 522XI Tractor the brake foot pedal has like over 4" of play. Its not a really big thing as you can take your heel and pull it forward I guess its just a lil aggravating more than anything. I just like everything to work as it should. Anyway I tightened the spring best I can but I still have slop. I removed the spring to ck it since it is a compression spring I wonder if it is collapsed and just plain worn out or even the right one? The Spring length is almost 4" long at 3.977,The spring outside  dia, is .790" and the wire size is .195". As you can see by the first picture the spring being a compression spring doesn't look like it can compress much maybe not even an inch?  Has anyone had this problem?     Thanks ~Duke

Is this spring at the rear on the right side? Have nothing on the 94-7906 original dimensions.

Service manual page 3-7 calls for 2" of free travel with the transmission in neutral.

I don't have the dimensions of the spring but Garry is correct with the two inches of travel. Released it is above the rocker pedal, and engaged/latched it is forward of the rocker pedal.

You should have a spring to pull the brake pedal back into position. Item 3 in the description.

Denny, I will get on Master Parts Viewer tonight and See If I Can Figure where in Sam's Hill It Goes or where it is (located)! I looked under there before but didn't see anything. 

 

Thanks To All  ~Duke

Once I find the spring and put it on I will compare with your Pics!

You should be able to see it by taking the cover off of the tunnel. Just 2 screws and it comes off.

Well I just came from the Stable and laid down a drop cloth and had my LED  droplight hooked up. I located the spring and worked the action of the Pedal back and forth. It seems to me that the pedal action could be free'er than it is. One note when I went to grease the pivot the other day I notice grease went in the zerk  fitting hard altho it came out both ends. I am wondering if there could be rust around the shafts? Grease it good for lubrication but would it be better to inject some thinner lubricant in there some how to dissolve any rust that may be in there causing friction? I want to be clear that the pedal moves back and forth but not super freely like it needs to. This tractor has had a TON of GRIMEY CRUD underneath the tractor EVERYWHERE. on the frame rails and in all kinds of hard to get places. It is obvious that maintenance and good housekeeping was neglected on this machine. The Pedal spring has tension on it but it still will not return freely. Any thoughts on this?      Thanks ~Duke

It's a chore to pull the shaft out but it does sound like its binding.

It entails removing the fender the tunnel and the footrests.

While you have it apart you can check out the rest of all the linkage and the lift bolts.

The bellcrank may need cleaning too while you have it torn down that far.

I'm wondering if the 94-2375 Plate-Pivot, Brake, or 94-2488 Pivot-Hydro are binding? Plus there are all the linkages back to the band and drum brake that could be binding as well. They are all on bushings so should break loose with liberal applications of grease.

Dang, I don't want to pull the DARN Tractor apart to solve this unless I gotta have to, I took the tunnel cover off and the spring is better seen from the bottom, Like I said the two main Pivots 99-4430 BELL CRANK AND BUSHING ASM and 94-2351-03 BRACKET-BRAKE or John you may be right Its hard to tell by the Toro Drawings but could be the ones You mentioned or the ones I mentioned they had grease fittings in them that's for sure. I was hoping I could somehow maybe take the ZERK out and flush out the grease and crud and get some rust dissolving lubricant in there and work the pedal and re-grease. I was hoping for an easier way of freeing it up. I will go out with Camera in hand and see what I can do and try some things.

 

Thanks ~Duke

This afternoon I took the Zerk Fittings out of 94-235103 Bracket Brake and the other one under the Tunnel cover and took a heat gun heated them up a bit and shot some brake cleaner in them by using the heat gun it pulled the cleaner in just like flux on a solder joint. I then blew in the Zerk fitting to blast out any GRIME in there. I repeated the procedure with the heat gun this time using sea foam penetrant working the brake pedal back and forth and they both freed up quite a bit. I then cleaned the Zerks and replaced them and shot grease in them both. They are both much better and now I don't believe I will need to pull back on the pedal to engage  the cruise control which was really a nuisance.  Thanks for everyone help and Ideas.

Glad to hear that you seem to have solved your issue. These are well engineered machines but like anything mechanical, require routine maintenance.

Thanks John, I know you got a bunch of them and are a good resource for information.
