Actually, by following P.E.'s procedure you possibly could get a pedal. What happens, even sometimes after using the old fashioned two person method, air bubles will work their way up and out. I have bled brakes before that were marginal, and the next morning, they were rock solid.

If your problem IS the grommets below the reservoir, I don't think this would be your only problem. I assume you added fluid, and any leak above the cylinder itself would not introduce air below that point and would not in itself cause a soft or no pedal.

To replace the grommets you will simply pry the reservoir out of the grommets and then pry the grommets out of the cylinder, then push the new grommets in place with your fingers.

Good luck,
