Two-person job.
Engine off.
Guy with wrench gives the orders.
Scripted like this:
Mechanic yells "push on the brake"
Wife steps on pedal with 'stopping-in-garage' pressure
Mechanic opens bleeder valve (that has a clear plastic hose jammed on the rounded end of the bleeder and dipping down into a Coke bottle) 1/4 turn and waits for the wife to yell "it's on the floor", at which time...
Mechanic yells "hold it there" while he closes off the bleeder. He then yells "let it up"
Wife lets it up and yells "OK"
Mechanic yells "push it down" and repeats the exercise - being mindful that after a couple of these innings, the reservoir will be empty and the whole scenario will need to be repeated.
Ideal: Pedal should not be pushed all the way to the floor, as it allows the pistons in the master cylinder to move over new territory -- which, for newer vehicles is no problem, but for aged ones, might mean that corrosion or crud in the piston could result in a subsequent leak. Ideal pedal travel should be 1/2 way -- which is totally controlled by the guy with the wrench UNLESS it was so full of air as to allow the pedal to go to the floor without any hydraulic resistance.
Too much pressure on the pedal when bleeding the line will result in pushing the left/right cross valve (there's a name for it that has slipped my mind) to go off-center and favor one direction -- causing a brake light to remain on (which can be corrected by the similar scenario while bleeding the other side -- and closing off the bleeder when the light goes off.
In general -- if you're just changing fluid, use enough pressure to cause fluid to be pushed out -- but not enough to move the switch/valve.
