I'm rebuilding rear brake master cylinder from KZ750F1 1983
Bought new dust seal and cannot get it installed- seems to be too large for housing
goes on piston ok but when I try and push it into the housing groove it does not go well
I lubed it up with DOT 3 fluid before installation-- could it have expanded when wet with fluid?
never rebuilt a brake cylinder before-- could use some expert advice-- will have to buy another new dust seal as it got torn with all my attempts to get
