Ok, I noticed a brake pedal squeak that's definitely inside the car. I'm assuming it has nothing to do with the TSB as my brakes are basically brand new all the way around and the sound has persisted throughout the change. Humidity makes it worse, but it's fairly prevelant all the time. I've heard everything from just a rubber/metal noise to possible brake booster issue. Is there another way to diagnose the brake booster? My ESP would cover a booster, but if they check out the squeak and it's not the booster, I'm gonna get charged up the butt.
Thoughts?
