Reading the Bentley manual it seems that it is necessary to have a PST2 thing connected before the brakes can be properly bled on a PSM equipped car (2001 S).

Is that correct? ie., can a good solid pedal be obtained bleeding manually? Or is there any other altenative to a visit to the local Porsche dealer?

To bleed the ABS you do need a PST2 or PIWIS.

Most folks do not think the at the amount of fluid in the ABS controller is significant enough to worry about. I agree, I own a PST2 and I usually do not bleed the ABS. Especially if it is just a normal flush and bleed.

Unless you have replaced whole parts or lines there is not reason for any air in the ABS system. Most dealers that I have watched don't bleed the ABS either for a normal brake flush service.

This thread is in line with the questions I need answered. I have severly corroded calipers/rotors. Can I remove my calipers and reinstall them without needing to hook the car up to PST2?

Yes, but I would bleed them twice. Since you will no brake fluid in them at all when you re-install.

BTW... I deleted your second post ont he same subject - please do not double post.

Loren,

Since you seem to be the only one that responds...

I think I read on here somewhere that if you push in your brake pedal and rig it to stay pushed in and THEN remove your calipers the brake line won't drain out?

Doesn't matter you still want to bleed the brakes. As long as you don't open the PSM or ABS lines they do not need additional bleeding.
