I literally just did exactly this.. Had the BRAKE warning light on the dash and replace rear brakes on Idrive message on my 2019 X3 M40i at 32k miles.. rear rotors looked fine to me.. they were smooth and not grooved.. so i bought OEM ATE PADS and a BOWA rear brake sensor.. $128 shipped from Pelican parts and i was charged 1 hour of labor ($135) at my local Indy shop.. as others have mentioned youtube is your friend.. just a rear pads replacement is a pretty easy job w basic tools.. I should have done it myself but I decided the $135 cost was not worth my time and effort.
Best Brake pads for BMW M4
Akebono for low dust.
I love the Ferodo DS 1.11 that I use on my M4. They're noisy and the dust is epic but they're totally fine to drive to and from the track. I've used them at a few track days at California Speedway, they're wearing really well, and I've never had even the slightest fade.
I have EBC Bluestuff on my M4. I think they are a good hybrid pad, and fine for sprint or autocross, but they will melt as an endurance pad. Sessions longer than 30 min on brake heavy courses and they will glaze.
It’s almost as if spirited driving causes wear.
