Ah yes, the awful squeal noise on my 2020 GMC Sierra Denali HD (2500) is familiar. I've had my pads replaced once and the squeal came back quickly. I am looking for an aftermarket option and prefer EBC brake pads and rotors, but they don't have any pads for the 2020+ HD trucks. I think that GM screwed this one up BIG TIME with the consumers, but what do they care, because vehicle demands are way to high and customer service has suffered. I was in shock when the dealership pad slapped my new truck with the service bulletin. At least the rotors should have been turned.
