[LAP1DOUG]

I use a pair of surgical type locking forceps (a great tool to have on many occasions) to grab the plastic cup part on two opposite sides, and pull hard while twisting a bit.

I always suck out my old fluid first. Otherwise you are just diluting the new fluid into the old fluid when you bleed. A Power Bleeder is great, and I use that too, but only after filling the reservoir with new fluid.
