Just picked up a new Sierra Denali that was being delivered to a dealer recently. I didn't want to wait 6 months to order a truck, so I bought what came on the carrier. Nice truck, and I like it much better than my 2017 F-150. Came with a 3.0L diesel. This thing sips fuel compared to my gas engine. The only complaint I have is the braking....it sucks!!! Anyone tried those Brembo Brake upgrades? Only do the front or all four? Other brake upgrade recommendations? I'm open for suggestions. This is such a big difference in braking that it scares me to tow anything.
