I have a 2017 GMC Sierra 1500 5.3 crew cab. I hear a clicking sound from the rear when brake pedal is pressed. It’ll make the sound when I’m pressing it to slow down and even when I’m not moving and press the pedal a bit further. Took it to a dealer and said a part( can’t remember the name) needed lubed and said it was common. It’s still making the same noise. FYI I do not have drum brakes and rotors look and few great and plenty of pads left. Anybody ran into this issue?
