Sportsman brake problem, help needed...
New to forum and in search of some advice on this repair.
I have a 2001 Sportsman 500. Recently, the front wheels lock up after only a few minutes of riding. My 4wd doesn't work (Hilliards?) so I cannot place it in 4wd to "force" it to go.
If I leave the atv alone for 20-30 minutes, the wheels will start to rotate again but only for a little while before locking up again.
Any suggestions/experience with this?
Thanks in advance,
The sympthom is tipical for a vehicle that has brake pads touching too much on the disk without breaks being aplied. This is usualy due to dirty/rusty break cylinder in one of wheels. What hapens is that on one wheel (usualy front one), the pads are locking a bit, and as you drive the bike, it develops very high temperature in the breaks oil due to a friction. As becoming too hot, oil expands too much and causes the cilinder to actuate like you've aplied the breaks. After some time, it cools down and "releases" the breaks. My sugestion, lift up your bike and rotate wheel by wheel by hand and see if they're all rotating freely. Then aply the brake, release it and rotate again. Repeat the process few times. You're looking for the wheel or wheels that will start feeling a bit dificult to rotate. If you find the wheel, there you go. You'll need to rebuild the cylinder on that wheel.
But first of all, before doing anything, make sure that new oil is in the brake system and system is without any air.
