I am sure this will make someone smile.

I have tried warming, it lubricating, it and stretching it,,
all with no success. The seal is so small I simply can not figure a way to slide that seal over the top lip of the piston. I am sure someone on this forum has the answer:

sounds like you have the wrong seal? is it identical to the old seal? if so, how did you remove the old seal?

It does sound like the seal might be the incorrect one? I normally warm the seal, lubricate both the seal and the piston with brake fluid, then use a blunt, smooth tool to encourage the seal to stretch over the diameter of the piston before sliding it down into place. The only time I had this not work was when I tried to do it in a cold garage in the middle of winter, and the seal snapped. Try to avoid this, because the only way to source a new seal is to buy an entire new rebuild kit....ask me how I know.
