I have a 99 AC 300 4x4 and my dad has a 2000 AC 300 4x4 and they both have very bad brake squeaking sound. Not when you are applying the brake but when your just riding. ANyone else have same prob and or any fixes for it? Thanks

 

I know someone who had a similar issue on a Suzuki KQ and he replaced his brakes and it stopped for a few rides and then returned. He then replaced the brakes again and checked his disks and found the fronts to be warped. after replacing them and the pads he still had issues.

He finally replaced the front bearings, the brake calipers and another set of brake pads. Once he had them burnished no more noise. I cannot say which part it was for him pads, disks, calipers or bearings.

If it were me I would take it for a short ride around the house making sure I still heard the squeal and try to isolate it to the front or the rear. Then start by taking the wheel off and looking for clean brite rubbed metal. You do not hurt anything by taking the wheel, brake caliper, pads, hub, bearings off.

I can tell you that if yo have ridden them much in mud or sand the seals are probably worn enoughto let water into the bearing. Easy to check and fix.

Hope this helps
