So I just got the front brake pads and rotors replaced along with a caliper on one side but I'm still hearing a crunching sound sometimes when I speed up and slow down. It seems to go away once I stay at a steady speed. Sometimes it seizes up a lot worse than others. I know very little about cars and I was hoping that someone here might be able to at least point me in a direction or tell me what I should look at. Thanks in advance for any help!
