My department has purchased 3 2015 Tahoes (PPV) and have less than 5,000 miles on them. The brakes are squeaking terribly and the rear rotors are pitting on all 3 Tahoes!! Has anybody else had this issue and if so, how did you fix it? I'm fearful that the dealership will simply apply the "no squeal" garbage and say its fixed or they'll just send us packing after they say "there's nothing we can do". Anybody have any suggestions?

 

I am assuming this is not an intermittent squeak but rather is occurring at every brake application. All 3 vehicles or just one?


Are you in a rust belt? If yes, you should be buying vehicles with rear drum brakes.
were the brakes were overheated due to severe use? Pad roasting will glaze them and they will squeal all the time.


regardless, other than replacing parts, there is nothing that can be done at a dealership level.

 

Yes only when the brakes are applied and yes on all 3 vehicles and we are in Alabama so no salty roads or sea salt issues here. My city does not have an interstate nor are these vehicles abused (2 are admin vehicles and not patrol and the other is mine to which I take home and nobody else drives).


After a short search, I've found that this is a common issue with the PPV vehicle for some reason and, in my opinion, should be fixed/remedied by the dealership. These are brand new vehicles and not abused like you would think a patrol vehicle would be.

 

Might be worth having them checked to make sure they are lubed properly, I've fixed tons of brake squeals just simply cleaning and lubricating the right spots


You'd be amazed the stuff that comes from the factory sometimes.

 

I'll bet PPVs have a heavy duty pad (read very hard, maybe ceramic) which would have a tendency to squeal.
