I have thought before that it could be the vent hoses because I go in extremely deep water, like up to the racks and play in it for sometime. I have had water in the front and rear diff but just drain and change a couple of times and it's cleaned out. One of my friends said I should have gotten the yellow rubi cause I ride it in the water so much it would look like a big duck.

 

I'd say that is your problem then; either the vent hoses from the drums are missing or torn, or they are too short. You can buy hose and extend all hoses (3 brake drums, and 2 differentials) up to the upper headlight housing.

Strange you would have such trouble, I do alot of mud riding and like I said earlier I've only had a problem once with the brakes, and occasionally have to change the differential fluid.

 

If I didn't stay in the mud so long it might not be much of a problem but I will get a rincon and have honda put the willwood disc brakes on it so I don't have to worry about them. Then all I will have to do is change the pads every few thousand miles and it will not require so much mantenance. There is nothing wrong with the vent hoses, they are in good shape, I just think it is the way we play in the mud around here.
