Hello, just recently I swapped out my old rotors and pads for brand new drilled and slotted rotors and brand new ceramic pads. Recently, I started to notice when I’m about to come into a complete stop, my brakes start to squeak and they make a very high pitched noise which is really aggravating because I just got them; any ideas of what the problem may be?

 

I had a similar experience with the "Pterodactyl" scream of a squeak when I replaced my rotors/brake pads awhile back. I had the big brakes for my 13 G37 Sedan. I forgot to pull the spacers from the old rear brake pads and put on my new ones. Car squealed like a banshee coming to stops until I fixed this, specifically for my rear brakes.
