I have a '99 ES300 that's been as trouble-free as one could ask for. It's also been treated very well and has pretty low mileage (~75000 miles). During a routine oil change (non-Lexus dealer) I was told that the rear brakes needed attention. Only 3mm on the pads and I was quoted $346 to replace pads, rotors, which includes labor. My inclination is to have serious work done at a Lexus dealer so we asked for a price from them. We were quoted ~$300 for just the pads and labor. We were also told that rotors almost never need to be replaced but, if they did, it would cost another $300 or so to replace them.
Here's my question ... is it the case that rotors almost never need to be replaced? Are Lexus rotors made harder or so much better that they last for the life of the car?
Note: My wife and I aren't 100% certain but we believe that we have never serviced the rear brakes before.
Thanks.
