I'm having problems with the front brake on my polaris scrambler. Its the front right brake and its not clamping the rotor when breaking. I have changed the pads and bleed the brake of all air several times. It clamps the rotor tight enough that I can tighten my lugs with my breaker bar without the wheels turning when the quad is parked, however when im trying to slow down when riding my quad that wheel will just roll.

It makes for some pretty hairy experiences on the trail.

 

try adjusting the little hex bolt on the top pin that holds the pads. turn it in until the pads are just touching the rotor then back it out a hair. that may fix your problem

 

thanks for the tip, I tightened that bolt down, but I'll try it again it definatly can;t hurt.
