I purchased my first atv about a week ago and its a Sportsman 850. I have about 150 miles on it and there is a significant clunking noise when using the rear brake. There is also a loud clunking noise when going down a steep hill and applying hard pressure to the hand brake.

The noise is coming from the front right of the machine, I would guess right around the area of my right foot. Its a blatantly obvious clunking/rattling. Called the dealership, they "haven’t" had similar complaints and said they’d look at it, but I just wanted to check here first.

Any ideas? I’ve read a lot on the forum about clutch noise, etc., but I’m brand new to these machines and am not familiar with different noises.

Thanks!
Phil
