Brakes on 1850

[Anonymous-0]

I know this has been discused many times, & it is not rocket science on how the brakes work on my 1850, but here goes I need some idea as to why they continue to lock, app 2 years ago I put new discs on both side cause one side was locking up everything worked great for a short period of time started locking up so I took apart and cleaned the balls & greased everything worked great for a short period of time, then started locking again, I installed new springs and cleaned and greased the balls everything worked great again, now they R locking up again. I am sorry this is so long but I need some ideas as to what I can do. Thanks in advance Johnnie

I recently replaced the brakes on my 1850 and they worked great until I powerwashed it and thenlet it set outside and dry a few days. The water got inside the housing and oxidized the discs and actuator. I took them apart, wire brushed the discs off and then made sure I greased everything back up. I also put a small bead of grease on the housing plate so it would repell water from getting in there again. Also, you may want to shorten up your brake actuator travel by removing shims. The more shims, the more likely the water to get in there also.

I have no shims, & no oil leaks,

by lock up do you mean that the brake disc when actuated does not brake ? if no internal leaks, then the non-asbestos discs may release fuss balls which smooth & dull sides that they are grabbing against. when you take off cover are they dull ? maybe try another set of discs.

by lock up I mean, when appling brakes they grap and will not release

Sometimes mine need attention every year and then it may go several years before I have to take them apart and clean them up.

Not a big job just a pain because I only notice them not releasing when I need to use the tractor now not tomorrow. Bet that is the way with most people. ^D
Pix I took to show someone.

Two ideas..If you have to use it tomorrow, when
then brakes lock up back up a couple of inches.
Pain in the a.., but usually works.
One time I ordered some oversize balls for the
accuator. Can not remember the size I used and
I will post when I remember.

there is a service bulletin out and they changed the linkage on the brakes to help that on the 1850 so now we need to know what you have old style or new style. I will try and look for the serial number break today.

We've more than one 1850 Oliver here.
most noticeable was the improvements later models over earlier ones.
Now that you've mentioned it had brake trouble both of the early ones. Trouble might have been trouble with the balls continued oxidation. Got fed up with them and replaced those one inch balls with ONE INCH STAINLESS BALLS.
I've also quit using grease as it collects dust wear and gum's up the workings. Have opted instead to using POWDERED GRAPHITE (seed corn-planter lubricant (John Deere). Just a little dusting will do it.
These have been my braking ways.
Also, my two cents is usually different from somebody else’s. Take it or leave it.

I agree 100% with the graphite!. Never tried the stainless. There was a bulletin on drilling holes in the linkage and then the shim kit. It all helped.

John I have one that says they changed the linkages entirely and have different part numbers but no mention of shims my 1850 has the new style.
