On stock pads/rotors, do people notice far more brake dust on their rear wheels vs front? When I wash the car, I always notice significantly more on the rears and almost none on the fronts. Trying to see if this is typical experience for these cars as I have intermittent issues with brakes occasionally feeling like I'm driving in the winter. Dealer reported no issues twice. I was wondering if fronts weren't grabbing like they should be.
Rear Brake Dusting

Nope, tons more dust on the front wheels on my car which still has stock pads on all 4 corners.
Did you buy your car new or used? If used, perhaps someone wore out and replaced the front pads with lower dusting aftermarket pads but the stock pads are still on the rear.

Bought used @ 8k miles, that seems super fast if they did swap pads. Sitting at roughly 22k now. That's a fair point though, I'll check.
What's the easiest way to check them? Does it show somewhere on the pad that doesn't require dismantling the brakes to check?
I'd think the dealer (2 separate ones) would have mentioned if they were aftermarket while checking for brake issues, but shrug

Your typical used car brake pad inspection only requires checking remaining pad thickness, not checking the actual brand of pad that's installed.
8K on a set of pads would be rather premature for most drivers, but not if the previous owner used the car hard on the track... or if they purposely changed the front pads to aftermarket pads that dust less than the stock pads because they wanted to keep the wheels cleaner.
Only way to possibly find out what they are is pull the front pads and see if there are any manufacturer's marks on the pad backing plate.

So only numbers I could see without pulling the pads (no time right now, and I need to figure out right way to do that) were on the side of the pad facing the front wheel center. D1405 2017031. Didn't return anything when I googled whole thing; first half I think is the brake size as it returned a bunch of brake results from multiple manufacturers.
Can anyone confirm they have those numbers on their brakes as well?

From what I recall the stock pads should say Brembo on them, have mine lying in a bin somewhere but a quick search shows these:
I saw that pic in my searches, but I don't see any numbers on the inner curved side. I attached a pic that shows where I'm seeing the numbers I posted above. Disregard the dirt, it's been nasty here. I can't tell if the back plates say Brembo as I haven't taken it apart.

D1405 is the pad backing plate size, and the other numbers are probably the manufacturing date.
Not the information you need unfortunately, you're going to have to pull the crossbolt and pins and slide a pad out to look at the back side... and hopefully any identification information hasn't been worn off from contact with the pistons.

I guess what's your end goal? Most of your braking is done with the front pads, if they weren't grabbing you would have to mash the pedal with every stop. If you think there's even a question just go out on an empty road, get up to about 40-50 and hit the brakes reasonable hard - you should feel the weight shift forward. If your issue is with the brake dust (understandable, the stock pads dust like crazy) - get some aftermarket rears.
Issue isn't with the brake dust. That's just me noticing the difference, which when coupled with occasionally odd braking response, makes me wonder about if fronts are fully performing.
Sometimes the car just feels like it keeps going despite pressing the pedal (and then further depressing it) especially when compared to the typical feel and stopping distance expected driving it daily. I can't always replicate it. To me it reminds me of driving in snowy or icy conditions where you keep going forward if you try to brake too hard in those conditions.

Do I need a caliper tool or anything if I try to pull the pad to look at it?
Nope, just remove the bridge bolt, 2 pad guide pins, and spring plate, and the pads should slide out provided you don't have a lip on the rotors. When reassembling, I believe the bridge bolt torque is 24 ft/lb.
Stock brake pads on these cars are made by Ferodo, so you might see Ferodo or Brembo on the backing plates if they're OEM pads.
Before you replace pads you need to find out what the problem is. The rear pads should show significantly less brake dust so the fact that you see more means there's something going on. Maybe one of your rear calipers are seized up. Either way, get it checked first because new pads will wear out quick is there's an issue.
I'd suggest bleeding at all 4 corners if you're having issues like that and it's intermittent. You really shouldn't need to at such low mileage but it's a free fix that should be easy to try.
Not looking to replace right now, especially since pads have plenty of life based on what I can see and 2 different dealers inspecting for issues. No signs of glazing etc. One commented they look like new. Just following a suggestion from above to see if the front pads are the original or not.
If I bleed them I'd have to at least top off brake fluid though, right?
You should buy some fluid so you can top it off yes, but you're not really going to lose much fluid bleeding them unless there's a ton of air in the line. Unless the previous owner did something stupid, there shouldn't be.
Do you have the PDR option in the car? If so, use it for a while and see if this occurs at any point. Review the video (helps to know approximately when it happens during the video) and check the application of brakes and gas - two vertical bars at the top right of the video. While autocrossing with my size 15s, I've had a few instances where I thought I was in the marbles and not slowing like I thought I should be. Review of the video shows that I has applied both brake and gas at the same time - OOPS!
Well looks like you nailed it. Powerstop Extreme are whats on the fronts. Any experience with these? Certainly explains the low/no dust.
