Bleeding master cylinder

I like using bent steel brake lines when "bench bleeding" the master, with a short clear section so you can see bubbles. The plastic tubes can come free and spray brake fluid everywhere. Some MC's come w/ a really cheesy bleed kit that doesn't screw in, but you just push in the port holes and hope friction holds them. You may have to pump the pedal 50 times to get all the air bubbles out. I always do it on the car, not on a bench. I can push the pedal w/ my foot and crane my neck to see, but I am 6'1". Otherwise, I would pay my daughter $1 to push, or tell her it is a competition called "push the pedal".

I know a geyser can spray fluid past the reservoir lid seal, but still seems bad since if fluid can get out, moisture can get in. I have a newer MC w/ plastic reservoir on all my old Mopars. They seal better.
