Change that Brake Fluid

A complete flush should eliminate the gunk. Tell us were you are at and I am sure you will get many local shop recomendations.
I also wonder about the flushing alternative, but I do want to keep the ABS feature alive. From the mechanics' descriptions, the ABS system has tiny openings in it that they claimed warranted replacement. I guess they're saying that flushing won't work, even without trying it first.
I know that dealer's mechanics are prone to recommending more the the minimum required to fix things, but I don't know just what to do in this case; clearly the independent shop didn't pick up on the gunked brake fluid while the dealer's mechanics did.
5 hours to make all the changes seems reasonable to me (though I am NOT a DIY when it comes to cars except the normal fluid level and tire pressure checks).
The price of the parts from Porsche wouldn't be any lower at an independent shops, would they? Or am I just naive?

Porsche will make you pay list price for the Bosch unit. You can get these generally for about 3/4-1/2 the cost at an independent (and they are about $2000 list for a non-LSD model) as a generic Bosch part. I have never had a bad 993 unit, but Tom W here on the board had one on his 964. We did EVERYTHING to fix his braking problem from new master and brake booster (it already had all new upgrade calipers) and quarts of brake fluid flushed through. Nothing work for a firm pedal until we replaced this ABS unit. It listed for $2600, but we got a used one for around $400 and it worked great. Good luck....

She just traded in her car for the 993, paid the difference, and drove it away. No PPI, I don't think she even drove it until it was time to leave the dealership.
And yes, we're still married.

As far as fushing is concerned a little info here. WHen you flush the system, you need to REMOVE the bleeder screws from the caliper you are bleeding instead of just cracking it open. You should PUSH the pedal with the bleeder screw out (holding a rag over the opening) which will push out (oh yeah) any wax plugs, gunk, etc. Anytime you have a lazy bleeder screw, you should check it this way yo see if it is plugged up.

Good talking with you a few minutes ago,....
My apologies, sir. We do not perform street car maintenance or repair work. We've confined ourselves to race cars and street high-performance parts & services of every kind...
From your list, the ONLY places I would take a 993 are (in no particular order):
Stuttgart Autotech
Marque Motors
Motor Sports International
MSI should have thoroughly flushed the system (pressure bleed & cycle the ABS) when they replaced the master cylinder. If that didn't fix it, they should have offered to replace the ABS controller since that would have cost less than having the Dealer do the same things.
Please keep me posted on the outcome.
*********************
Just a note here; Bob is right: Porsche's brake maintenance intervals (24 months) are absurd and this situation is living proof that annual brake flushes are FAR cheaper than buying these expensive components. I'd strongly encourage ALL 993's owners to buy a pressure bleeder (Motive's work fine) and do this yourself every year (or more, if you do DE events). Its the cheapest proactive preventative maintenance you can do besides oil changes,...

Jim,
It may be worth the time and $40 to pick-up a power bleeder, a quart of brake fluid and try Viper Bobs method. It certainly can't hurt. One tip, flush with a different color fluid to be sure the old fluid is completely expelled.
