Master Cylinder Rebuild


Old MX Racer
The 05 450 needed a fix on the master,ordered up the rebuild kit,and low and behold the rubber seals do not come on the piston!Well trying to stretch the seals over the cupped,razor sharp edge at 4 something in the morning proved to be a nightmare!Finally got it,but man,other than ordering a new unit,how the heck is the PROPER way to install these little buggers????
