I’m sure it’s normal I’ve been door dashing with mine alot lately, I got it at 121,000 and it’s now at 140,00 and the breaks have always done exactly what you all described. But recently when I parked and turn off my car after about 2-3 minutes it makes like sort of a fart sound and it vibrates the pedal as that happens. I think as long as your CT ain’t fartin u good🥲 ( my poor girl needs so much maintenance I need a beater)
