On their Suzuki that is! My brother in law has weird noise coming from the front wheels. It sounds like a grinding noise, not high pitched squeeking, and only when going below 10mph. After that it goes away. It makes no noise when using the front brakes, just when taking off. I kind of think it might be a speedo cable or something. It's brand new with only about 100 miles on it. Any ideas? Thanks, Chris

 

it's under warranty, take it to the dealer and let them fix it

 

He did, they couldn't find anything, we couldn't get it to make the noise for them. As soon as he got it home and started it up and drove off the trailer it started to make the rubbing noise. Thanks, though. Chris

 

No I don't, but I have an idea of what it is... did he ever do any mud running or water crossings with it?
The new models are suppost to be water/air tight but if there's something wrong with the seals on the front end there could be some water/slit on the brake drums and are starting to eat away at them and there could be small stones (slit) rubbing in between the brake drums and the rotors on the brakes... if it's under warrantee take it back to the shop and tell them to have a look at it, and most dealers you can't trust so someone stay and watch them and once they have the brake drums/rotors off, take a look at them and see if there's any sign of rust/grit/wear.... if so tell them that you want the seals and rubbers replaced on it... (It's 4wd I presume?)

Thanks, I'll look at it for myself first and see if I can find anything wrong with it. Then he'll have to take it in and see what they say. I'll look at it so they can't feed him a bunch of bull. This is his first ATV, he doesn't know much about them. Thanks again, Chris

 

Chris, I'm still learning about how bad these brake systems are myself. But you should notice, when you take the brake drum off, a rubber seal on the brake drums edge, all around the circumference. Look closely at the grooves in the seal. Do you see any debris? Now look at the springs which move with the brake shoes. What do you see there? If there's a lot of mud, rust or water, you want to do a thorough cleaning of the brake system. I always start with the rear brake because it gets most of the crap. Get yourself some brake pad cleaner, water proof grease, wire brush, medium sand paper and compressed air. You can clean the trash out of the seal with a small screw driver but be careful not to damage the seal. They are very exspensive. Clean the "O" ring and clean all the mating surfaces of dirt and other foreign material. There's an air vent on each of the brake backing plates(front & back). Blow compressed air in them to clear out dirt and water. Use the sand paper only on the drum mating surface and brake shoes mating surface. When you grease, be sure not to get grease on either of these surfaces. Grease the seal, "0" ring, and shaft assembly as being assembled.
Do the same with the front brakes. The greasing of the seal is very critical since the grease is the only thing that locks out the water and dirt. I find, the dirt stays out if you can keep the water out. But who's going to avoid water? Certainly not me... I hope I didn't miss anything but if I did, just email me and I'll try to fix it. Have a good time riding after the work is done...
