I have the 2014 Sportsman 570. I don’t ride much, not rough on this machine at all. I recently took a short 5 mile ride on a level trail, 2.5 miles up the trail I noticed my hand brake getting ‘spongy’. I stopped and looked for anything noticeably wrong, nothing I could see, no wet spots of fluid or anything. I turned around and headed back out of the trail, by the time I got to my garage I basically had no hand brake at all, brake handle would depress all the way to handlebar. I removed the cap and checked fluid level, it was low but not dry. Checked underneath for fluid leaks or anything broken, no fluid leaks and nothing broken that I can see. I added fluid and still no brakes. Decided to bleed the brakes thinking somehow air got in lines. Bleed brakes for over 2 hours and cannot get brakes at all, brake handle still depresses all the way to handlebar. By the way, this is the hand brake only, foot brake works fine. I am NO mechanic, maybe I am bleeding the brakes wrong or is there possibly something else that could be the problem?? Any suggestions?? I am not on here too often but please leave any suggestions and I will get them as soon as possible. Thanks.
