The sled is a 2012 std rmk with 1800 miles. I bought it for a back up sled when I got it home I noticed the brake was really spongy so filled the reservoir and bled them thought I had fixed them. Took it to Cooke city and was riding and I flipped over backwards. It payed upside down for awhile and when got it up right no brakes. Took it back to trailer bled brakes again added fluid worked good for the rest off the week. Took it out for a ride yesterday and brakes slowly faded away to nothing and there is no visible leeks that I can see.
