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
