99% of the time I go to a mechanic, dealership, etc., to have periodic brake work done they tell me I need to get new rotors. Doesn't matter what brand of car I have because I've owned many makes and models over the past 20 years. I've grown accustomed to being told 'you need new rotors' no matter what. Even of the rotors aren't scored or warped, they always manage to make an excuse that I need new rotors, and hence my bill goes from $200 to $800. Only once in the past 20years has a service dept ever offered to even turn the things. I always 'need new rotors'. Acura, Nissan, Honda, Chevy.....50,000-150,000 miles. I "always need new rotors". I've changed by own brake pads/rotors on cars in the past and simply don't have the time, but not being a mechanic I can't really respond to somebody with my car on a hoist and pulled apart and claiming the every tiny groove on my rotor means my car is unsafe to drive and I need new rotors. Case in point, the brakes on my Mazda M3 with 65,000 miles have just started to squeek, which obviously means the pads need to be changed, but I dread going to a mechanic and have them tell me "I need new rotors". Given my mood and the economy, if they are simply trying to screw me, they are going to pulling their impact wrench out of a certain orifice. How often do you really need new rotors?
