brakes don't work

I"m having problems with the brakes. These are supposed to be heavy duty brakes but they don"t work at all. I opened up the chamber to look at them, and it has alot of oil in there. The pads look worn but still very usable. I was thinking of drilling a hole in the brake chamber to allow the oil to drain if any was to seep in. Any body have any thoughts? These are dual acting disc brakes (supposed to be dry) on a 1964 fordson super major diesel. Thanks,

Ther is also a proceedure for setting them correctly.

If it is leaking through the dif lock shaft there is an "O" ring on this. It will mean taking the bull pinion shaft out and removing the dif lock mechanism, removing the shaft and replacing it. This could be a bit of a job. I would not advise trying to let the oil out of here, there is your life at stake if you don't do a proper job and stop the oil getting in. IMHO.

The shaft should pull out when you have the brake housing off. I would put a couple of bolts back to hold the inner housing in place and to keep the shims lined up.

Any tips for the pad replacement? Is there a special tool to punch the new rivets?

Back to the oil, These brakes always remained dry ther was never any oil in that area in service unless there was a seal problem.

IMHO? In My Humble Opinion ;0)

The brakes come in a kit with linnings and rivits. Re-lining is not a common thing in the U.S. I'm sure there is a place I could send them, but I bet I can do it myself also.

I also suggest changing that seal. IT may look good but the oil came from somewhere and it will pay in the long run not to overlook any possibilities. And seals are pretty cheap.

I can't see how it would hurt to drill a hole to the lowest part of that cavity, either. Lots of them on other makes of tractor had a special drain hole to channel the oil away from the brakes if the seal leaked. There might be one in there already.
