I am new to the forum here and I apologize if this has been asked prior, I tried searching, but came up empty. I have a 2020 Sierra 2500 Denali and for the past 5k miles or so I have had noise in the rear. I learned there was a safety bulletin on the rear brakes due to noise, but because I was out of the B2B warranty and it was not covered and would be an out of pocket expense. With my son in the business can do the work, so I went ahead and ordered and paid for a set of brake pads and now have been waiting for almost 3 weeks. The dealer told me that GM is not releasing the pads (I suspect unless the dealer is doing the work) and that they have no expected date of delivery. I'd like to stay with OEM, any recommendations on where I can locate a set would be greatly appreciated. Or if anyone has a recommendation on a good aftermarket set of pads, that would be appreciated as well. Rotars are no problem, I have them, just waiting on the pads. Thanks.
