Front brake size 2021 Premier

How can I identify which front brakes I have short of removing a wheel? I'm about to replace the factory brakes at 65k miles, probably with PowerStop units. I've had great success with them on my other Chevy products.

You need to know your RPO code for the front brakes. There are two different size rotors If you scan the QR code on the driver door jamb, it will show you the codes for your vehicle. You can also talk to the dealer parts department.

So looking through all the vendors I can find with brakes categorized by RPO Code, I only see J 60 brakes (my RPO Code) listed for 2017 and 2018. I have a 2019. What gives?

I suspect the data base is not updated. There should be no difference for 1018, 19, 20, 21. I measured mine to sure.
