My Friend had his brand new 4wd kodiak 2 weeks and the back brakes were already to the metal. He put new ones on for 30 some $ and he stoped using the back brakes. after 2 more week there already wore out again. Whats up with that? does anyone else have this problem?

I have a 2K Kodiak with 100+ hours on it and the rears are fine. I don't baby them. I have co-workers with Kodiaks that are doing ok too. One of them has a friend that has the trouble you speak of. I have since purchased EBC pads in preparation.
I would drain the fluid and bleed them real good. If the fluid is contaminated or has air the heat may expand the fluid and push on the caliper. Then I would read up on adjusting the rear brakes and give them just a tiny tad more slack.
If that does not work I would blame the materials.

 

Yes your right they do suck,but my dealer gave me the second set of rear pads for free,he is getting alot of the bikes he has sold back for this problem.He is putting it all under warranty and fighting with Yamaha about the problem.At least my dealer stands behind what he sells if Yamaha won't. Just like the blue plastic on the Kodiak my dealer told me & put it in writing that if they come up with A solution to the problem I will be looked after. I guess that's why I keep going back to this dealer.

 

I'm Having the same problem with mine. I have put alot of miles on the bike, but hardly ever use the brakes at all. the fronts are fine, But the rears are metal to metal. I'm taking mine in tommorrow the dealer says if he finds somethig wrong he will fix it for nothing. The machine is less than 60 days old, they should not be worn out yet. But when I asked the dealer about it he said that this is the first he has heard of it. The funny thing is he has pads there that Yamaha sent him and he did not order.

 

Mine goes through rear pads quickly too. I also went through a mudhole about 6 inches above my floorboards, had to be towed home, and spent the next 4 hours cleaning about 5 lbs of mud out of my main clutching. Very disappointing.

 

Some folks have found the ducting clamps for the clutch housing to be loose letting water & Mud in.
As with any ATV check ALL the nuts and bolt for tightness you can.
I've had mine up to the seat many times for minutes at a time with no poblems.

 

I have had my 00 Kodiak for almost a year and have road well over 100 hours in places ranging from Utah, arkansas, oklahoma (little sahara) . Aside from regular oil changes and adding a pipe I have not had to turn a wrench on the bike. Its been the best bike I have ever owned, I have owned a few something like 7 Honda's 2 suzuki's 1 kawi., and 10 Yamaha's since 76'. I wounder if riding in 4wd and engaging the rear brake only, since in 4wd mode the rear brake is also having to pull the front wheels to a stop via the drive line might cause this sort of problem. I ride 95% of the time in 2wd thus puting less stress on the rear brakes than when in 4wd. when in 4wd i use the front brake almost exclusively since the front wheels each have a brake and the drive line will force the rear wheels to stop. I hope that makes some sense.

 

On about 300 miles of hard riding, mud, water and hills, there has been no problems on mine. The brakes still look good also. Many factors can contribute to brake wear.
