I run stock fluid in the 996TT and I run Castrol SRF ($70/can) in the track appliance; same rule applies to both.
Leading evidence: 'Run stock fluid in the 996tt and i' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace (usually 4-5 yrs depending' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

It's not end of the world but I'd do it every 3 yrs for sure instead of waiting until pad change (usually 4-5 yrs depending on mileage).

I just got a coupon to change the brake fluid on my '02 996.

1) Do I really need to change brake fluid every 2 years?

Suggestion
I bleed my system everytime I change pads as well as track weekends when I already have the wheels off but for a TRUE flush I heard that you cannot just pump the brakes or use a power bleeder because of the ABS.

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.

I just got a coupon to change the brake fluid on my '02 996. Dealer recommneds every 2 years. Special price is $169.00
1) Do I really need to change brake fluid every 2 years? My mileage is 15,000.
2) Is $169 a good price for our cars? Or can I take it to an independent?
Thanks.
If you don't track the car, once every 3-4 years is all you need if you have no symptoms of spongy brake pedal. Every 2 years is overkill for most drivers. For street driving, the rule of thumb barring any symptoms, is with brake pad change.
I do it every 2-3 yrs. There is a risk of rusting the ABS sensor as well as inefficient braking. It's not end of the world but I'd do it every 3 yrs for sure instead of waiting until pad change (usually 4-5 yrs depending on mileage).
Its every two years regardless of mileage if you want to follow the factory recomendation. You could drive zero miles and the brake fluid is still going to absorb water.
Yup,
My 996TT sat in storage for 16 months (don't ask); brake fluid was flushed pre and post storage....zero miles on the fluid.
As has been said, it's all about moisture content.
I run stock fluid in the 996TT and I run Castrol SRF ($70/can) in the track appliance; same rule applies to both.
My dealer sells the Porsche brake fluid at $23/bottle. It's good for one flush plus some left over. $99 seems very good price! You can also do it yourself or have an independent shop do it.
What about the ABS? I bleed my system everytime I change pads as well as track weekends when I already have the wheels off but for a TRUE flush I heard that you cannot just pump the brakes or use a power bleeder because of the ABS.
Just to emphasize what Sloth said and explain the science of Brake fluids. Brake fruid is a Hygroscopic liquid which mean it absorbs water over time. Not only will this affect your braking over time but the moisture lowers the boiling point of the fluid and causes internal corrosion in the brake system.
Change it every two year irrelevant of mileage, track use, etc...
Yes, in order to do a full flush of the system (racing ABS or the 964 C4 ABS included), you need a PST2, Bosch Hammer or PIWIS in order to control the channels.
However, even if you don't do this, the small amount of brake fluid left in these channels compared to the rest of the system, by volume, should not make a great difference, but it should be done nonetheless.
No problem.
Just remember, no rebadging your brake fluid to make people think you're running Castrol SRF when you're running stock fluid
Sorry everyone, inside Cayenne forum joke
