Brake flush... Really??
#32
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

This list is far from comprehensive but helps with why I made my selections.
Endurance Racing - Castrol SRF
TT/HPDE - Wilwood 600+
Street Car - Valvoline Synthetic or ATE Superblue (Not Blue Anymore)

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)

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 !

Yea, last time I flushed was in September. I will test for moisture to see where I am at.
