I don't have PSS or TC. Just the ABS. In the ABS, there are 3 parts I'm considering. (1) There's the proportioning valve on the side of the ABS, (2) there's the main ABS itself (with the ~5 brake lines flowing in & out). That thing is a nebulous black box...a new Porsche parts costs about $3K, but a used one can be found in EBay for maybe $30. (3) Then, there is the piece along the sidewall. Porsche calls that the intermediate piece. I'm not sure what it does. The vacuum comes through this piece and there are 3 different steel lines connecting to it.
I'm guessing one of the three pieces I listed there must be the culprit by process of elimination.
Since I have two boxsters and one of them has a perfectly normal brake, I'm considering swapping pieces off of the working boxster until I can eliminate the problem. My worry, though, is that I end up with two Boxsters that have brake problems.
