By the way and since you guys are talking about brake fluid..... any specific brand that you would recommend ? There must be some brands that do better than other under hard driving conditions.

ate 200 gold is all the brake fluid that you'll need for a street car and for most entry level track use. if you insist on more, motul rbf600
During the CPO of this car November of 2019 they did new front pads and rotors. Based on that it would seem as if Im good for another year. I will do the moisture test and Youtube up on the flush process.
Just remind me to ask you about your brake fluid status the next time you drive behind me on a coffee run.
I do every oil change so a small portion of the old fluid stays in. I don't usually do the inner bleeder unless I happen to have the car up on quickjacks for something else.
Be careful with that, only using the outer will push contaminates through the passages potentially creating a blockage or allow them to coalesce on the outer portion of the caliper as well as not flushing the entirety of the inner body. This is a good practice as it increases the frequency of the change but must be accompanied by regular service intervals.
I bought a 2013 model sometime in 2016 - it only had 10K miles then - so potentially no flush job for about 4 years.
The brake pedal sucked. The PO may never have noticed because you get used to it progressively. At the time I had no lift so I had the dealer do it for me, same time as a COV, and I think it was $200-250 maybe, no muss no fuss and the brake feel went from ho-hum to spectacular. I would agree that 2y might be a bit overkill, but 4 was too long clearly, mileage be damned.
In that vein, funny story, I was doing a DE at Sebring in a 996 back in the day, a car I had just bought and been told was serviced recently. You can hit 130-140 at the end of the back straight in that car. Un-noticed by me, focusing on my lines and dicing with my group, my pedal was getting lower and lower (in hindsight that is, at the time I thought I was suddenly messing up my heel and toe and blaming myself, didn't realize what was happening). Until I got to the end of that straight at full tilt, pressed the pedal and... nothing... Fresh underwear moment.... Pump pump pump, abort the turn, pump some more, and eventually flicked the car sideways and somewhat flatspotted the 4 tires... If I wasn't stupid enough, I then left the track (to clean my undies presumably) and almost crashed the car while parking in my spot in the pits (still no brakes - forgot, adrenaline) - handbrake moment (a big no-no on hot discs). Since that day, I change my brake fluid every 2 years or so on street cars and I don't take anyone's word for a service. (more often for DEs cars but don't track my 991 - it's too valuable for me vs my old aircooled track car)

oofta. Growing up with a track+daily 911 in the family, that thing saw a brake flush before and after each track day. Surprised you didn't convert to this strategy after that event!

Oh I did on the track car, except that time obviously where I took it on faith.... I was talking about the 2y interval here. I no longer track my car - so 2y is fine for street. For track, every DE is smart, yes, or every month if like me you went twice a month - haven't had the heart to get up at 4AM anymore and drive for hours, tech in the AM, and wait for hours before my run group ;-) I'm sure I will again soon once I find a group that lets me show up at 9AM and drive ! Also been chicken re: value of my 991 vs my old $15000 track 911 !

Endless RF650 or Castrol SRF. Have Endless in my car currently.

Awesome stuff - but remember that this also needs be flushed more frequently to do it's job. Great insurance for a track time but like a lot of specific track items it does need more maintenance.
Yea, last time I flushed was in September. I will test for moisture to see where I am at.
