Master cylinder appointment complete that fixes the squeaking sound from the brake pedal. I was denied any help from PCNA for good will since I am out of warranty although I am at 46K miles. Therefore, I was totally prepared for the sticker shock originally quoted $1,495 to "start" for this repair. The part came quickly that probably indicates that these type of failures are common and these parts are stocked in the US vs. having to be shipped from Germany as others noted. The time that it takes to get this completed is 6 hours per Service Manager and did not seem to require brake fluid flush as others noted, but I was due for it and asked them to do it. The actual invoice came to be $2,500 plus $195 for the brake fluid flush and they kept the car 2 days since they were pretty busy.
