s550 rear brakes noise low speeds
hello all,
just picked up cpo 2015 s550 beauty of a car. Only problem is at low speeds 15mph and under I can hear a light screeching sound almost like a metallic sound. Noise doesn’t happen while braking and seem to be non existent when speeds are higher than 20mph. Dealer says it’s normal? Anyone else have this issue?

You have posted on the W220 forum, so your 2015 S550 is well outside our usual discussions.
IF the dealer actually checked the brakes, and the pads aren't worn out...
For brakes in general, one thing to try is what the techs call "burnishing the brakes". Find some empty road. Accelerate to 60, brake very quickly to almost a stop, immediately repeat four or five times. Drive home at moderate speeds, and let the brakes cool. That often will cure the squeaks.
Pressure-washing the brake calipers will also often stop the squeaks for a month or two.
