Hi All -
I've been lurking around the forum for while but this is my first time posting. I am looking for some advice on an issue I've been having with my clutch. Specifically my clutch master cylinder makes a squeaky sound when the pedal is depressed/released. I verified that the sound is indeed coming from the master cylinder - it is not the mechanical creak that can sometimes emanate from the helper spring or clutch pivot points. The clutch itself only has around 14k on it (car has 32k, clutch was replaced early when IMS was done) and there is no change in clutch function. The pedal feel is mostly smooth and normal with no change in the engagement point. The only time I think I can feel slight resistance is when feathering the clutch, but this is very minor. The problem seems to have started after a brake flush at a local, reputable Porsche shop. The shop only flushed the brakes - not the clutch - and used ATE 200 fluid. I've read that 9X7 gen vehicles can get master cylinder squeaks when non low viscosity fluid is used, but the LV fluid doesn't seemed to be specced for the 986. Obviously the squeak and flush timing could be completely coincidental. Has anyone else seen this before or have any advice on what to do? Any help is greatly appreciated. Thanks!
