I have a new-to-me 2011 SLT with 142k miles. Kinda figuring out all the quirks of this car at the moment. Currently wondering about this brake pedal noise. I've read other threads about it, but no videos to compare the sound to mine. Is this what others have talked about? Do I start with a brake flush, and then move on to master cylinders and brake booster from there? Or is this just spray some lube where the pedal is bolted in?
