I'm making a second attempt at rebuilding a master cylinder for a Trail Boss ATV. I lubed all the parts with brake fluid, but had a lot of difficultly getting the lip of the U seal into the cylinder bore. I ended up damaging a part of the seal lip. On my second attempt I have tried "walking" the seal in but it just doesn't want to go without undue force. I've considered building a "funnel" out of thin sheet metal to get it started and I've considered relieving the cylinder lip to make it easier to slip past. Just seems like there has to be a better way.
Any advise?
Thanks
