The manuals also say you need to hold down the clutch pedal when bleeding the clutch. You don't need to do this unless you have just replaced the master cylinder.

Tool Pants, does this hold true for the 987 too? I thought you needed the PST2 for the 987 Boxster.

PIWIS is the replacement for the PST2 and is needed for the 2005 up cars.

I am not up on the 987/997. I did speak to Peter once about bleeding the brakes on the newer cars and he said he did use the PIWIS. I do not remember the details as it will be a while before the newer cars show up at our work on cars days. Peter said it was a 997 but it might have had PASM or something like that.
