I am about to replace my brake pads for all 4 points for my ATS 2013 Luxury, and found out that Brembo produce P09004N pads that looks like a good substitution for genuine GM ones (p/n: 22791925), especially for the price of ~45$ (compare to ~205$ OEM).
For what it's worth, rockauto.com has the 22791925 (ACDelco 171-1107) pads for $147.79, so don't feel obligated to pay your dealer's inflated price. Actually, it'll end up being about $140, as you can find 5% off discount codes for Rock Auto on this forum or elsewhere on the internet. Note that 22791925 is the JE2 "performance brake lining" pad compound. There's also the
non-JE2 pad, ACDelco 171-1165 (GM 22866931 or 23145627) for only $111.79 ($106.20 after discount).
And of course there are a number of pad options from other brands.
The rear pads were only available from the dealership.
There are plenty of rear pad options on the market. Even if you insist on running the OEM pads, you can get those from rockauto.com or Ebay or Amazon or whatever. ACDelco 171-1114 is the non-JE2 pad, and 171-1113 is the JE2 compound.
Hopefully. I bought the AC Delco pads for the rears and they're a dusty mess.
Which "the AC Delco pads" did you get? 171-1113? 171-1114? Or perhaps the non-OEM ACDelco pads, 17D1659MH (professional grade semi-metallic) or 17D1659CH (professional grade ceramic)?
