Sinking brake peddle even with a new master cylinder
I started this thread on the 6speedline forum about a sinking break peddle. I haven't gotten any information so I decided to try this forum. See link below for the initial problem.
The break peddle on my TT drops quickly to the floor with pressure. Me and the dealer thought is was a master cylinder. The dealer put in a new master cylinder and the peddle still sinks to the floor with continued pressure. It has been not a instantaneous sink, but pretty fast, about 4 seconds to go 80% down.
The dealer will contact Porsche but he seems to be at a loss for the next step.
Has anyone heard of this? I'd like to give a suggestion to the dealer. They don't know what to do right now. Thanks.

I just had exactly the same problem with my 06 997 C4, which I left with the dealer to replace the master cylinder. The dealer gave me a brand new (1300 miles) loaner Cayenne meanwhile and, guess what, its brakes do the same thing! I'll receive my car back by the end of the day today or tomorrow. Let's see if they solved the problem.
