Greasy Brake Bands

I posted this in another area but I figure I will get more input here. I am replacing the brake bands on my tractor. I took the axel off and discovered that the brake bands look fine. There is plenty of pad left on the band and the movement / operation of the band looks ok. I also checked the brake drum and it is in great shape. I checked to make sure the drum was not spinning on the axel shaft and it was not. I am not sure why the brakes were not working. The bands and drum were covered in greasy dirt. I know the grease would prevent them from gripping but I thought that as much foot pressure as I had put on the breaks that it would have at least shown a little resistance. I did not drain any transmission oil before removing the axel and I noticed the transmission fluid was level with the bottom of the seal, according to the manual it should have been higher. I guess the seals could have been leaking in the past and it drained to the bottom of the seal. The leaking oil could have coated the brakes and caused the problems. I am going to clean it all up and install new seals. Any other experiences or suggestions?
 
check the wheel bearing's for wear if there loose they let the seal open oh the bottem.
older fords are notiorus for that. check how to tighten the bearing . and check the vent for the differantial old art

Replace the seal and there are severa; ways to clean the band. I have used a steel brush,brakecleaner,solvent and sandblasting them it all depends on how bad they are with the oil. The lees messy method is the wire brush. In the last 15yrs i have done a bunch on the A,B,C and SC
 
Grease on a friction surface reduces the ability to stop. I have never had much luck cleaning the grease out. It gets "pressed in". I'd change them. Your description indicates they are probably saturated. If you haul loads downhill you can find out real quick how bad you need clean, dry linings. Hope this helps. Gerard
 
I learned this from an old Packard and later AMC dealer. On brake shoes that are soaked with brake fluid or grease use the flame of a small torch and slowly heat the linings, this will boil the contaminates out of the lining and as they boil out just use a rag and keep wiping till nothing more comes out. This was before the modern type of brake material and the brake cleaners. I have tried it on tractor brakes with good results that would not clean up with brake cleaner but I think they were the orignal brakes of the late 40's early 50's era. Have also done that with the rear brakes on a car as well and the car he used to show me how to do it was my 1960 Rambler Classic 4 door sedan.
 
The tractor is a 1979 Long 610. The bearings look good but when I pulled the shaft seals out they were definitely in need of replacing. I have removed all the grease from the brake drum and the housing but am still working on the bands. I am pretty sure these are the original bands. I used sand paper on the bands to remove the outer layer but I am concerned about the points Leroy and ASEGuy brought up about the grease being pressed in the bands and not being able to get it out. I put the bands on the drum last night and compressed them with a wrench and was still able to turn them on the drum. Not a good sign.
 
We used to soak them in Carbon Tet. (spelling? ) but I dont know if you can buy it anymore, It did work though
 
Well I gave in and ordered a new set of brake bands for $100. I would rather do it right than have to do it over. Unfortunately it is hard to find parts for the Long’s and I have to order them over the internet and even at that, there are not that many places to go to. Hopefully will have the oil seals and bands by this weekend so I can continue working on it.
 
i use a small charcoal grill to "cook" the oil out...works good...set the rack about 2 inches above fire...slow even heat so you dont overheat the glue holding friction material to band...i let em cook till no more oil oozes out.
