Update: Did the pad slap. Car stops fine with no odd noises.
I was surprised at how crusty the calipers and caliper brackets were for a 2018 car. At this rate, I wonder if the calipers will by seized by the time of the next brake job lol #SaltBeltLife
Also, does Hyundai use Sil-Glyde on the caliper pins at the factory? The original grease was yellow like Sil-Glyde.
