Booked for service and brakes. Told me the cause of the scraping in the brakes was from a stone and the noise would eventually go away. I asked if it was safe to drive and he said and I could replace front brakes and rotors now for $800 or could wait for next service . Noise got worse and q week later took it to another mechanic who showed me the brakes and rotor and it was so bad and he told me it was not safe and was quoted $400 to do the same work .
