Konur

I have the same problem as Ronnie Jones. At low speed (like in parking lots) the brake is hard as rock. Brake works just fine on the highway. I love my 2015 GMC Sierra. It has 322K and still purr like a kitten. No one seems to have an answer to this brake issue. I don't want to start replacing parts if it is not going to fix it. I looked into recalls but for some reason my VIN is not included in the recall. I saw posting someone replaced the vacuum pump that fix the issue but also someone else said that did not fix the issue. Anyone know the status on the lawsuit? https://gmauthority.com/blog/2020/03/lawsuit-filed-over-alleged-brake-booster-problem-in-general-motors-trucks-and-suvs/
