Brake dust
My car will not be here until september/october . Can anyone report on brake dust compared to a 991? Some previous owners switched to Brembo TS20 pads which apparently produced significantly less dustwithout compromising on feel. Anyone switched from oem pads?

My brakes are starting to make more noise like the pads are wearing down (not typical squealing noises) with 10.5k miles off street use. I’m curious how many miles you all are changing pads at with street use?
Will the car definitely display a replace brake pads warning light? Thank you

I can’t compare to a 991 but my 992GTS seems to generate a hell of a lot of break dust. I have high gloss wheels and they are ceramic coated so cleaning is easy enough but it only takes one journey and they seem to be covered again. It’s easy to say now as I’m not actually dipping my hand in my pocket but I think PCCBs would be a consideration if I was to buy again.

I continually am perplexed by discussions of brake dust. On my two white cars, I find it completely irrelevant. Neither car produces any significant brake dust. The cars themselves get dirty and need to be washed long before brake dust becomes an issue. I just use the same soap (Zaino 7) to wash my wheels and the car body. I autocrossed the 992 last weekend and the car was dirty from tire rubber specs, etc. and needed to be washed, but even when pushing to that limit, brake dust is completely irrelevant and it just washes right off with mild soap. I just don’t get it.

I have standard brakes on both my Porsches. I honestly can’t imagine any sports car producing less brake dust. Perhaps if you are comparing it to an SUV or family hauler (something I’ve never owned), you’ll think Porsches produce a lot of brake dust. I’ve always owned sports cars since 1977 and my current Porsches produce very little brake dust. I keep my cars extremely clean (for example, I recently sold a BMW and a 981 privately and both buyers told me that they’ve never seen used cars this clean.) My Porsche dealer who did the sales transaction told me the same thing. In fact the service tech wanted to buy my BMW after seeing how clean it was (with 80 k miles on it)
Also, it probably depends on your washing technique. If you take you car through a car wash (I hand wash), sure, the wheel insides won’t get clean. And once wheels get filthy, it becomes harder and harder to remove the dirt (but that goes for anything). But if cleaning your wheels is part of your regular wash technique, and you always clean the barrels as well as the outsides, than it’s absolutely a non issue.
Spyder with about 70 miles since last wash
992 GTS with about 50 miles since last wash

also be aware when washing, the iron rotors flash with a rust coating almost immediately. The rust then dusts off as soon as you hit the brakes and deposits a nice coating on your clean wheels. If you're not bothered by this then no big deal but it drove me nuts!
My solution was buying/specing cars with CCB's. Yes an expensive option on Porsche's but well worth it IMHO. It's also an option that will make the car more desirable if/when you decide to sell/trade. Cheers

This drives me nuts too! I now clean the car/wheels, then drive up the road to dry the disks and then dry the car. Certainly helps.

1 vote for tons of dust here. I have Aurum wheels and they are a different color in about 20 miles after washing. By hand. Barrels and all. I will be changing pads come spring.

Friend of mine recommended the Hawk Ceramic pads but I can't find them with fitment for front, only rear. He has a 991.2 and while better on dust with those pads nothing like what you describe.

Well, can't explain your experience but I think you are the first and only one making that statement. I hand wash only too, clean inner barrels spotless with brush every time yet - dust comes right back. Also, not sure why you link dust generation to cleaning...the cleaner, the faster you see it again. Tons of brake dust agrees with all other members I have read about here and on other forums. Also, makes sense for performance brakes like Porsche's Brembo. Why you see no dust - not sure.

Most of my trips are around 20 miles and I’d say I usually do a wash every 200 - 300 miles if there has been no rain. If the roads are wet or it rains, the car is immediately dirty and needs a wash. If I take it on a trip (anything more than 100 miles or so) I wash it the next day. I’ve never once thought brake dust was an issue or the determining factor in needing a wash.
I also actually really enjoy washing my cars and kind of look forward to it. But only my own cars….

Armor All Outlast brake dust spray. Unless you pay for PCCBs you will have some brake dust. Some "ceramic pads" are better than OEM. At the track I'm more interested in stopping and how long the pads and rotors last. I use the Outlast and the dust washes off easily. A properly bedded seat of pads and rotors will have a transfer film on the rotor and washing does not rust the rotor surface. Normal street driving will wear the transfer layer off and the rotors will rust when washed.
