front brakes going out when muddy

happens to me too, i think all the mud in the brakes is the problem, i usually rely more on my rear brakes when that happens

front brakes

I have the same problem too like you said it happens only when its muddy

this is something i have commented on before. years ago when disc brakes were coming into fashion on motorcycles, riders were finding out that when that exposed disc got wet, the pads hydroplane off the disc effectively making the brakes useless for a few moments. if you look at the front disc on most mid to late 70s bikes you will see a solid disc. the bike companies remedied this by drilling holes in the disc to allow water to escape. i have 2 ranchers with the front and rear drums and a foreman with front discs. the ranchers always stop better. i recognize that i don't ride in the same swampy stuff some of you guys do so i don't have the same problems with the drums leaking. if the foreman disc is not drilled, i would look at the possibility of taking them to a machine shop and having, about 3/8 holes drilled along the path that the pads follow. might be the cure. might also ruin your discs.

This may seems odd but, in a previous life I raced motocross around the southern US. The discs that has holes or slots are actually for DRY conditions, and the solid discs are for mud use. Odd as it sounds the holes allow build up of material (mud) between the pads as the solid disc is "supposed" to keep it out. If you watch AMA Pro racing on TV and they have a mud race you will see the majority of riders with solid discs for the mud races. I find it odd that Team Honda was one of the first to use these, and they don't put them on there Utility ATVs.
