So I got around to doing the flush today and Ill say thing thing worked like a champ. Aint nothing doing but opening up the bleeder and waiting for clear fluid. Close bleeder and move on. Hardest part was taking off the wheels
On another note, one review of this product mentioned the potential to hurt the braking system with too much PSI (at the max of the bottle, 20 PSI ) due to some components operating at ambient pressure (review was linked from the product companies website). This was on a Porche if it matters. Anyway, I didnt go over 10 PSI (as they thought was safe in the article). I didnt see anyting in my manuals about PSI maxes, so I stayed on the cautious side. It did require me to pump the thing back up once or twice, but whatever. Any thoughts on this?
Here is the section that mentions this:

The one-man system worked surprisingly
well. The only problem we envisioned
was that the unit pressurizes a
portion of the braking system designed
to work at only ambient pressures.
The car�s brake pressure is increased
by the movement of a piston inside the
master cylinder when the connecting rod
of the brake pedal presses against it.
The boosted pressure on the fluid is
immediately transferred to the caliper�s
pistons. The caliper pistons, in turn,
transmit this action to the brake pads,
causing them to squeeze against the
brake discs and slow the vehicle.
The tubes that feed hydraulic fluid to
the master cylinder from the reservoir,
however, are outside the pressurized system.
Thus, in a 911, they are merely
pressed into their receptacles on the
master cylinder with rubber grommets.
Subjected to the pressure of the Power
Bleeder, the passive seals of these tubes
could conceivably be ruptured.
While the instructions suggest keeping
the pressure in the tank below 20 psi, we
kept it under 10 psi for fear of blowing
out these feed tubes. Yet, even at this
lower level the Power Bleeder made
flushing the system extremely easy.
