All with the rear brake resivor mounted low. I draind all the old fluid out of resvoir,put new fluid in and bled the rear brakes till clean fluid came out. Brakes are like new again. All the Polaris with ther low mounted resivor really need to lengthen the hose and mount higher like the newer models. I think this would cure all the problems with rear brakes coming & going.
