How often the rotor need to be replace?

Rotor

Some rotors can be resurfaced and it is cheaper. Most brake shops prefer you buy rotors because there is a money factor and time involved.

The cost of resurfacing a rotor is around $15.00 each. Rotors on some cars are as little as 25.00 each. Is that price difference worth safety? In most cases the rotor has to come off of the car to be turned. There would be no change in labor to turn or replace. It actually takes longer to have your rotors turned. New ones are ready out of the box after cleaning them. Turning them takes 20 min. to a half hour each. Not good if your shop charges by time on the rack. At my shop, I prefer you buy new rotors because it is safer and the job is done right, the first time.

Hardly ever, unless the brake pads wear down to metal and damage it.Take it to a parts store and have them measure the thickness.



You must not forget about heat. There is a lot of friction on the brakes after all, that is how they stop the car. One job of the rotors is to dissipate heat.
Heat warps the rotors and also causes hard spots. Warped rotors will cause a pulsation in the brakes when they are applied. Rust is also a factor in replacing rotors. I have seen too many to count that have been rusted. I recommend every time you change pads or every other time at least. I know there is some expense there but, ask your self what is the cost of not stopping when you need to.
