I put new front pads and rotors on about 10k miles ago and they started squeeking after about 7k miles. I let it go, thought it would hopefully stop but it has gotten worse. I just bought a new set of ceramic pads today to replace the ones on there now. Just need to know if I should re-surface the rotors or just put on the new pads. The rotors don't look bad at all. Whatcha think? Thanks.
