Akebono Front Pads Rotor Wear

[EtotheD]

With less than 50 miles on the car I replaced the stock pads with Akebono ACT1001 front and ACT1878 rear. Really like the low dust for my daily street driving. The fronts are leaving a small outer edge rust ring that's not making full contact with the pad. Removed and inspected at 1k miles and everything looked good. Pad size and backing plate just like OEM and pad material goes all the way to the outer part of the rotor. Pads are flat and no grooving where the rust is. It's really a thin layer of rust. Added some lube to the pins but didn't help.

Maybe the pressure from the spring clip is keeping it from touching all the way and just needs more time to conform? It's like that on both sides and also the inside of the rotor. I think the pad actually skims the outer edge but not hard enough to make full contact and remove the rust. No issues with the rears and I'm just over 2k miles now. Recently tried bedding them in which normally isn't required for these ceramics but didn't help. Anyone else experience anything like this?

Probably smaller friction pucks. Pad braking pressure is far more than than spring clips.
I found the OEM pads dusted less after a few thousand miles, perhaps due to bedding in. Black wheels hide most of it anyway.
I've used Akebono pads on a CRV and they are less dusty.

Pucks are definitely the right size putting them against the OEM. Picture also shows the arrows pointing that they go all the way to the outer part of the rotor. What's interesting is when the rotors turn that orange tint from washing so does the outer rust ring. When I go for a short drive around the neighborhood to dry the rotors, it skims that orange tint off but not enough to get the rusted ring off. So its making contact out there but barely. I do notice its ever so slightly getting better. Maybe since they aren't as aggressive it will take more time.

How’s the brake feel vs OE?

Doesn’t bite as hard compared to most Brembo OE pads. Feels more natural like a standard vehicle. On other vehicles I’ve tried EBC Red Stuff and Carbotech 1521. Akebnono dust the least in my opinion.

Adding more findings. I took the pads out and you could see the rusty color on the outer edge of the pad. I measured the pad thickness and it was 8.5mm on the inside and 8mm on the outside, so .5mm difference. I saw a Facebook post with someone having the same issue on one side. His ACT1001 pads made in 7/25 and mine was having it on both sides made in 6/25. Bad batch maybe?

I saw NAPA still stocking the ASP1001 pads so I bought a set of those made in 2/23. Measured 8.5mm all around. Took the outer rust ring right off, no more issues. I guess besides checking the pad and backing plate shape I should have checked the pad height. Might keep the old ones to sand down flat later on or just toss them. Hope this helps.
