fill resevour with dot 3 brake fluid. Open bleeder and let drain. This partially fills the cyl. Have assistant slowly push the petal to the floor, open bleeder, let drain....but don't allow any air in. Repete cycle several times, just remember to check the fluid level. Once u go through like 3 cycles, have assistant slowly push in and out on the pedal, with 3 seconds between.....so.....kinda like this: push down, wait 3 sec, pull out, wait 3, pushin wait 3...etc....do that like 5 times. Then you feel how it feels.
If you've ever bled brakes....it's very very similar.
