3 Brake pads & rotor questions
2017 Carrera, 40K miles: Mostly street driving with several days a year of very spirited mountain runs. I may get to the track this year, but I haven't tracked this car yet. Brake pad warning message is on.
Gonna do brakes myself with help of mechanic friend:
1. Pads: Do we know who makes Porsche OEM pads? I'd sure like less dust. My wife's A5 Sportback hardly produces any (even when I drive it) I'd love to know what pads Audi is using.
2. Based on pics, should I replace my front rotors? I learned on RL that our rotors have wear holes. Mine are still visible. Based on the pics, should I replace them?
3. Any recommendations for aftermarket pads & rotors? Or sources for OEM outside dealer? Don't want to lose performance, but I spend way too much time cleaning wheels!

1) Pagid is an OEM. Genuine Porsche pads are likely a Porsche-stamped Pagid.
2) Pics don't show how worn they are. If the lip is substantial, I tend to replace. There is an actual spec for how thin the rotor can get before replacement, consider taking a measurement to determine this.
3) FCPEuro offers Textar and Pagid pads, at least for the 991.2, at a reasonable price with a lifetime replacement warranty. I'd just go with that.

Great info asellus, thanks much. For bonus points, do you happen to know the numbers on how thick the rotor needs to be?
What are your thoughts on Textar? My mechanic friend was recommending those.

I don't know off hand, but if the lip is like 2mm or more consider replacement. Let me dig around and see if I can come up with a spec quick here.

For the 991.1, the FSM states 32mm front, 30mm rear for new thickness, and the wear limit is simply -2mm, so 30mm front and 28mm rear. The rear rotor has parts interchange back through the 996 by the looks of it, whereas the front is unique to the 991.2 S model I guess. Regardless, 2mm is pretty standard, so I'd check there.
Worth mentioning as it's an interesting datapoint, the FSM states that if turning the rotors, the 34mm minimum thickness for post-machining (that is, for use with fresh brake pads) is 32.6mm, which seems to indicate an expected ~0.5mm wear on the rotor per brake pad change.

When I had my 981 BS I did a complete brake myself when it had 27,000 miles. I replaced OEM rotors and pads, believe I ordered them through Pelican Parts. You should replace ‘all’ hardware including the caliper bolts. This is spec. Also, make sure you get other specs like torque specs for caliper bolts etc. You’ll feel rewarded when you do the job 100% to Porsche spec. Important.
It’s actually an easy job and personally easier if done solo. And take your time. Car is jacked and Jack stands are sound! Safety first. Emergency brake is not enabled, otherwise you can’t remove rear rotor. Also, I had the dealership do brake flush after the job, it was around $180 and also met the 2-year flush schedule.
Here’s my order sheet for the BS. Your order should be exactly the same but part numbers for your vehicle. It took me about 2-hours.

I would have to guess your A5 brakes are Akebono. I've done brakes on a B9 S5 Sportback and they were Akebono.
My 991.1 OE pads were Pagid. The Textar OE replacements seemed to dust less than the Pagid.

Those wear holes are a good indicator that you have life left on those rotors. Mine looked similar when I replaced the pads a couple of years ago. No problems at all for me with new pads on same rotors.

Were the brakes on your S5 Sportback wonderfully dust-free? I'm amazed by how clean the wheels stay on her car. I wonder if Akebono makes 991.2 pads?

I thought OEM on 991.1 was a relabeled Textar. ..at least it was a few years ago
Yes, stick with OEM rotors, unless you're going to go on the race track with your vehicle.

I stick with oem pads and aftermarket rotors
Frozen rotors makes a nice product. I have been bitten too many times guessing which pads are oem and then having to redo the brake job because they sqeak. Been running stop tech and frozen rotors for a decade no issues.
