I recently purchased a car with 135k miles on it and I have no idea when the brakes were last replaced. I've done work on my cars before but never have changed the brakes, so I'm not sure how to tell if the brakes or rotors need to be replaced. What are the indications that the brakes or rotors are bad?
Also, a slightly different but somewhat related question: when I lightly used the brakes I hear a sort of "click click click" or "clack clack clack" noise that seems to come from the left front brake. It doesn't happen if I brake hard. What does this mean?
Thanks for your advice!
