About 3 months the car got new rotors and pads in the front - all Mercedes OEM. The new pads squeak like nothing I've ever heard before - the kind of resonating that makes heads turn about 1/2 mile before you arrive!

I've been back to the shop countless times - blue stuff on the backs, silicone on the pads, groves cut on pads... About 10 days later the squeaking is back.

I am at my wits end and just want quiet brakes! So, I'm looking for recommendations. Thank you.
