Polaris Sportsman ATV Brake Bleeding
I had to replace the front and rear master cylinders on a Polaris Sportsman, as well as pads all around. When bleeding the brakes, do I start with the front brakes first or the rear brakes?
John Talley: Whichever caliper you’re dealing with, I typically go with whichever one is furthest away from the master cylinder and work my way back. Now on that particular model I do believe you have a common system just on the hand brake, or maybe it’s the foot brake, where it’ll actually engage both the front and the rear. In that case, pick out which one’s furthest away and I would think that’s going to be the front. Start with it and then go to the back.
