2006 Polaris Scrambler - Problem With Brakes

[murph812]

Ok so i have a 2006 polaris scrambler 500 4x4 with a front brake issue. When the quad isnt running the brake handle squeezes normal. When i start it and ride the brakes act funny, i pull the handle and there is no resistance in the brakes, but if i pull the handle again they work great until i go again then ive got to repeat the process. Any help would b great!!

try bleeding the front brakes. get someone to help you when you do it, it makes it simple.

like bleeding the brakes in your car/truck ...

I agree, try bleeding the line.

I have another solution that a friend showed me. Check you bearings. When you are not moving the brakes work fine. Then as you ride the loose bearing allows the wheel to wobble and push the caliper apart. So the end result is that you have to pump the brakes a few times to get the pads back against the rotor.

I fixed the bearing on the wife's quad and now she has brakes again!
