2011 C63 AMG brake squeal

[Krom]

Hi folks. Existing pads are about 50 percent. Not sure of the brand, but they intermittently squeal. One guy was telling me that all pads for this car squeal - except for Porterfield. Another guy says that the current ones just need lube, and another guy says that doesn't work.... What does the brain trust here think? I mainly baby the car. No track work or backroads flings.

Make sure disc are good and install OEM pads from MB.
