2011 GM Sierra 1500 4we

For the entire 57000 miles of its life about every 6-10K miles the brake pedal will get low. The dealer has adjusted under warranty every time... Not to mention the three sets of pads rotors, drums, and shoes at different times they have replaced for pulsations.

Any one else experience this?

3 sets? GM was coming down hard on dealerships doing free brake work, after 12K miles......and you got two more sets?

So what was it they did to eliminate the low pedal, previously?

Yeah, if you word the complaint correctly they can do just about anything... Until just recently when the dealer now has to get approval on just about any good will.

They just adjusted the rear brakes. What happens it feels like the adjusters are backing off. If you hit the pedal twice when braking the pedal comes up. Yet I believe the last set of rear brakes they replaced the adjusters. I have not jumped in to look at it yet. Also the last time it was in I saw the striations in the left rear drum not concentric around the drum they went off to one side.
