For the last month or so I’ve been hearing a grinding noise when taking slow sharp left turns (sounds like it’s coming front front right wheel). Last time I drove my car I stopped at a stop sign and when I went to go again it wouldn’t, it felt like my brakes are still engaged. I had to floor it to pull over, I put it in park and back to drive and I could get my car home just fine. I towed it to the mechanic that is saying he can’t find anything wrong, I thought it was a seized calliper maybe but now I don’t know….any ideas? Thanks in advanced! Also it’s a 2009 Chevy trailblazer

    This isn’t really a diag, because I can’t do it over the internet, but it does sound like brakes were possibly holding. It has phenolic pistons that like to get tight and hold pressure, but sometimes act fine. There should be other signs that the brakes were hot though, edges of the rotors being a brick red color, white edges on the pads and such. Maybe take it somewhere else and have it checked for a second opinion.

    Also any chance you had the parking brake on by mistake?

      Thank you for commenting, I really appreciate your input :). I definitely didn’t have the parking brake on but I picked up the car today and drove around, the grinding noise was definitely quieter and only happened once and sounded like it was coming from the back now. The mechanic said maybe there was a piece of gravel in the front one and it got knocked loose when the tow truck lowered my car 🤷🏼‍♀️ my friends dad is going to look at it so we shall see. Thanks again!
