Just wondering if any body on here can help with an issue I am having with my rear brakes on a 2014 Grizzly the rear brakes are weak when I pull in the lever it goes almost to the bar and the back brakes will not lock up it does slow down but not like it used to. I have replaced the rear pads and discs replaced the fluid ( correct fluid ) and blead and no change in performance no visible leaks anywhere. Any thoughts could the problem be the master cylinder? if anyone has any suggestions that would be great. Thanks
