I recently acquired a 2001 Arctic Cat 250 2wd model. The front pads were shot so I replaced them. The rear pads are okay but they need adjusting bad. When you step on the pedal to activate the back bakes there is nothing going on. The rear brakes are mechanical and are activated by a cable like a bicycle. I've looked in my owners manual but haven't found anything on how to actually properly adjust the rear brakes. Do I adjust them at the brake pedal or do I adjust them where the cable goes into the brake assembly?
