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?
