Just a comment about the viability of the "suction"-type brake bleeders vs.
EZ-bleed. Remember that, under pressure, *more* air dissolves in the fluid
than at ambient pressure; i.e. when you pressurize the reservoir (and
eventually the entire system), you are forcing more air to dissolve in the
fluid. If you insist on using the EZ-bleed, you should certainly use the
minimum pressure necessary.
Conversely, when the suction method is used, not only is the fluid drawn
out of the wheel cylinders, but air that is soluble in the fluid at ambient
pressure is actually forced out of solution and sucked up into the device.
(For the same reason that a sealed bottle of pop has no bubbles, but when
the pressure is released, the gases start coming out of solution.)
The suction method has taken a few hits here recently because it requires
wrapping the bleeder screws with teflon tape or some other similar action,
but IMHO it's the method of choice for getting the "hard pedal".
