These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

I spoke to my son (an Audi tech at a Porsche/Audi dealer) about changing to ATE Super Blue brake fluid for track events. I used it in my 911 with good success but it didn't have ABS. He told me the Porsche techs, during their Caymen update training, not to subsitute this (or, as far as I know, any other brake fluid) for OEM fluid. Evidently, the ABS seals will corrode and fail. I don't know if this is an effort to sell more OEM fluid or a valid problem. No tech bulletin has been issued by Porsche but they are slow to issue these anyway. It's just a heads-up for those of us who do our own upgrades and maintenance. If and when I find out more, I'll update this message.

POST 2Original post

This sounds pretty ridiculous....There is nothing different about the Cayman S braking system than any other recent Porsche. Many of us who have tracked our cars have changed brake fluid, and no one has mentioned any issues. Only those who didn't change the stock fluid have anything to worry about at the track, imo.

POST 3Original post

no such thing. i use ap550 or motul 600 or srf brake fluid in my cayman all the time. dealer never said i can't and i never had fading bks.

POST 6Original post

Absolute BS.Super Blue is identical to ATE 200 except for the blue dye & both have been used in thousands and thousands of ABS equiped Porsches without any issues. However,Super Blue is no longer DOT approved becauseits dark colormakes it difficult to tell by color change if it's really, really old. Of course, I doubt Blue users leave fluid unchanged for more than Porsche's rec of 2 years.Some shops will no longer change to Blue because of perceived liability issues.

POST 7Original post

To all who responded, thank you. It's back to SuperBlue I go. When I had the '83 911 I changed fluid every 6 months anyway. I alternated blue and gold so I could tell when the system was completely flushed. Pete
