yea, they must be dragging somehow. your lap times if you raced would pobably greatly increase when you fix this.
No guys sorry it is my back brakes and no i am not dragging or riding the peddle.
Your caliper can be dragging without you knowing it. Put the quad on a stand and spin the back wheels and see if the brake is dragging. You may have to clean your piston inside your caliper, it could be sticking on you and not releasing quick enough. This will cause premature wear.
