560 disc brakes questions

Started changing brake discs tonight. First noticed the brake housing on left side was cracked. Quick fix would be to take housing off my parts tractor. It was also cracked. Can these be repaired or must I replace them? I'm sure a new one will be expensive. Also should I have the actuator plates machined or polished? I think they may be one of the reasons the brakes were always grabbing and maybe why the housing is cracked. The springs were weak enough that i could snap them off with my fingers. I got new ones. I really don't know what the ball track is suppose to look like. Is there a substitute for Case IH 251H EP grease? Do I put any grease on the actuator balls? Lots of questions but I want to do it right. They have been grabbing alot.

Lance: If you were able to remove springs with your fingers, I would say right there is the reason for grabing. No doubt the grabing probably is what cracked the brake housing.

These brakes should be cleaned anually if using tractor a lot. Never use grease on the balls, unless you wish to remove brakes and clean weekly.

Hugh, How smooth should those auctuator plate braking surfaces be before I put this back together? Mine are a little rough. Can the housing crack be successfully welded? The crack starts at the outlet hole opening and is about two inches long so it isn't to the braking surface yet. Do you just use regular brake cleaner to clean this?

Lance: The braking surface of the actuator should be very smooth as would be same for braking surface of housing. When you speak of roughness, are you suggesting corosion, rust, etc.? Or is it circular grooves caused by braking? I wouldn't worry too much on those circular grooves as discs will smoothly wear into those.

If that crack is not into the braking surface you can try welding it. You really have not a lot to loose on that. I suppose the other thing one should look at is cost of a replacment. Just maybe it is not worth welding. If welding warps it even a wee bit in the braking surface area, it will be quite useless. Those were engineered to have full surface contact when braking.

Just about any brake cleaner should clean those parts. I was quite surprised when you suggested you removed the springs with your fingers. I though, now there is one guy I wouldn't want to annoy to point of a physical conforontation. My experience has been those springs break before they become that soft. Someone must have got the brakes very hot at some point, probably what cracked housing as well as removed temper from springs. Always was one thumb rule with Farmall disc brakes, if they lock or jam on, stop and back a bit, they will release immediately. If you keep driving they never let go. When these were new most of us had graduated from machines that didn't work that well. Most younger folks never knew those machines that didn't work as well.

on my 460 i had to replace the springs and the ball tracks should be smooth,if pitted and rusty the balls can hang up causing the grabbing,i put them in dry they get worked pretty good if you use it and they should keep clean and rustfree,if you do use a grease the brake dust just tends to stick to the grease then you have a mess,as for the housing i have seen people weld them how they work i don"t know,i"d probably check salvage yards for a different one.

The balls are nice and smooth. The tracks may be worn but I don't know exactly what is acceptable wear to compare it to. Should the actuator faces be as smooth as glass and can they be machined or polished?

You can get used housings and actuators from places such as Steel Wheel Ranch or Bates Corp. I don't think new ones are available. Yes, you can have them machined, I just sand mine. Depends on how badly pitted they are, and how much you are going to use them. I would try sanding them, if they don't work well, consider machining. I have done this on two tractors. On one, even with new disks, I have very little adjustment left, so I think they were previously machined to where they can't be machined anymore, or else the new disks were too thin (aftermarket). I will disagree with Hugh (slightly) on the grease. I use a very small amount on the balls, not enough to contaminate the disks, go easy on it.

I was just thinking of using a little graphite on the actuator balls. There shouldn't be very much dust inside the actuator with all the dust covers on the housing and most of the dust being generated by the disks is to the outside surface of the actuator not the inside where the balls are.

Lance: I think the graphite would be a great idea, as dust will not stick to dry lubricant. Most of the 17 years I had my 560D from new, it was operated at 90 hp, with 16.9x38 tires, and we pulled a 13' Vibra Shank cultivator with levelling harrow or a 12 foot disk with 18" blades. All tillage work was done with these in ground turning on headlands. This puts tremendous presure on brakes using them for turning. Headlands tend to get rough if you don't do this, and on a dairy farm with 4 years hay in the rotation, rough headlands are a nono. Every spring my guess is we took a table spoon full of dust from each brake. Brake discs only lasted a couple of years in these conditions. Any kind of wet lubricant would create a build up on balls and ramps. I've been there and done that.

Probably ok. Be sure to use the rubber boots that the rod goes thru, if missing they are still available. Mine had oil from a bad seal, but so much dirt inside that the oil didn't even leak out.
