PSM and brake fluid flushing

[mikehkang]

Thanks for the prompt reply San Rensho and Eric.

What concerns me is the following description from Pelican.

"For cars with traction control or Porsche Stability Management (PSM), you need to use the Porsche System Tester 2 (PST2) in order to activate the valves in the hydraulic unit during the bleeding process. If your car has a “PSM off” switch on the dashboard, then you will need to go to a shop that has a PST2 so that the brake system can be bled properly."

I've also read other instructions that say, while not ideal, I can flush PSM equipped car without the PST2.

SR and Eric,
Do your cars have PSM?

Also, yes, the power bleeder IS the way to go.
Perhaps you do the same but I don't fill the power bleeder with brake fluid.
I use the bleeder to generate pressure and fill the reservoir in the car.
While this method takes a little more time, I always have my power bleeder clean.
