04 sentra 1.8 rotors

shouldn't be at 34k unless they are warped beyond repair, didn't change the front rotors on my 92 SE-R till it had 115,000 on it.

It depends upon the brake usage and how hard the brakes are used. I've seen people ride the brakes constantly (their reflexes must not be too good). I've seen others brake everytime they see a car coming the other way. I've also seen people accelerate up to a red light then brake hard instead of coasting to the light before braking. My 95 Sentra went to 70,000 before needing front brakes (disk front, drums rear).

Thanks for the replies. I di believe I will advise her to pass on new rotors and just get pads. I really think that rotor replacement merely a money maker for dealer at this mileage.

The rotors should be turned to 'true' them up if pulsing. Pulsing is a warning that Maximum breaking (the pads are bouncing over the surface) may not be available when you need it.

Replace is when there is excessive wear or multiple turnings :-/ or cracks. Severely warped (beyond truing) is a 'defect' in my book.

My 2001 Sentra had warped rotors at 70K with half the pads left. I brake very hard and then get off the pedal. I have 90K on rear brakes and not close to needing replacement.

Nobody but dealers replace rotors when there is no vibration felt through the steering while braking.
