I have an '04 450 Foreman. It's bone stock and gently riddenI have about 200 miles on it.The problem I'm having is the front right wheel grabs before the left one. There is no water in the hub as far as I can tell. I have crossed a few streams but it has never been in water over the center line of the wheels. I have removed the little red plug and rotated the wheel so the opening is at the bottom and I don't see or feel any water. I have also tried to adjust the brakes as per the owners manuel. Still no luck. the left wheel does grab it is just that the right wheel locks up first. So what do you think? I don't have much experience with drum brakes so any help would be appreciated... Thanks.

Like you I have had the same problem, so far I have found water in the other side (the one that does not lock up) and it can appear dry and fairly clean looking through the hole, to know for sure take the cartter key out and put a 22mm socket on the hub nut.....hold the break lever and take the nut off, than wiggle and pull the hub off and see for sure that it is dry. ( you may have to back the ajusters back a couple of clicks if the hub is draging the pads when trying to pull it off. other things that can cause this problem........
Check the cross over brake line for a dent (one on each backing plate) a dent can cause fluid to return slowly, keeping a brake cylinder from returning all the way, also a collapsed rubber brake line, or a problem in a wheel cylinder it self, but on a 4wheeler that new I would not think any of the three would be a problem, I would be looking for water to be the cause.

Okay, I finally had time to pull the drum and check to see what was wrong. Turns out there was nothing wrong with the left brake it was the right one with the problem. Water had gotten past the wimpy grease seal around the drum and since I don't have time to ride every day it had set in there and rusted the drum itself. I got everything cleaned up using some brake cleaner and a little fine grit sand paper, went down to the auto parts store and got me a good quality marine grease and did the best job I could sealing around the drum. I went ahead and cleaned and resealed both front brakes. I took a good long ride afterward and everything worked just fine. I did some water crossings and after I got back home I checked again for water in the drums. None so far. I hope what I did fixed the problem.  |

Darrell,
Here is a great read about servicing the drums I got from another forum.
I use Amsoil synthetic waterproof grease on mine, but you should be in good shape with the marine grease you got.
I know several people I have talked to have said that honda doesn't do a good job of filling in the seal with grease from the factory. Other people say it is useless to put grease in the lip of the drum. From my personal experience, I had much the same problem you did with my bike. My drums were so rusted, I had to have them turn. I also had subsequent problems with rust in one of my bearings. Since I have learned about greasing this lip I haven't had any problems with rust and crude in my drums, and my bearings are doing good.
You are probably not gonna like this, but you might want to pull that drum off again and pull the bearing and take a look at it. It is quite possible you have water in there also.
Good luck, hope you got it all straightened out.

One side might be adjusted different than the other. Check and see if the side thats grabbing grabs when you trun the hub if you can get it off the ground. If so, back it off a little so the brake works but doesnt grab. I have one side grabbing but i havent backed it off cause in 3rd gear i can grab it and turn on a dime so no backing up.  |
