I have a Case 580CK (with power shuttle) and am having an issue with the left wheel locking up.
I removed the brake housing and the pads and with the cover off, the wheel would turn fine. With the pads uninstalled, I put the cover back on (with the drum still installed) and again, the wheel would not turn.
I pulled off the drum, replaced the cover, and again, the wheel would turn. I now believe that the drum was pushing against the housing.
When I pulled the drum off, I noticed that there was no set screw to hold the drum on the splined shaft.
So this all leads me to the following questions:
1) I know that the brake pads pull around the drum to slow it down (providing braking) but how does the drum work in this system. Is it meant to push out against the cover?
2) What has actually failed here and needs to be replaced? (the pads are in really good shape)
3) Why, when the brakes are fully depressed, does the tractor actually hard stop (like there is a mechanical stop - which I assume to be the balls in the drum and gear assembly) This probably relates to question #1, but not sure.
Thanks for the help...I love working on this tractor but there are some new workings that I have never been exposed to before.
