New Rotors vs Resurfacing Existing Rotors

SDI_CTA-LeaseBuy-Ebook_728x90

There are not many things on a car that last forever. Brake rotors, like brake pads, wheels and many other items, eventually wear and go bad. The rotors are used every time the brake is applied so how they wear depends on a lot of factors such as the type of brake pads on the vehicle, the efficiency of the part, the type of vehicle, and the driver’s braking style. When you need to address an issue on them depends on all of those factors, but eventually, new rotors vs resurfacing becomes the question.

 

Rotor Details

New vs. Resurfacing RotorsMany rotors are thick enough that they will last through several brake pad replacements. Sometimes, the rotors are thinner to save on cost. Either way, the rotors will eventually wear down to minimum thickness specifications and they will need to be replaced or resurfaced. There are other causes to address with rotors as well. Sometimes they will wear unevenly and be completely ruined.

Corrosion can also cause the rotors irreparable damage. This happens when the vehicle is not driven very often and sits and allows rust to build up. Heat is another factor that can affect how brakes and rotors perform. When the brakes are pressed, friction results and the brake pads rub against the rotors and cause heat. The heat is absorbed by the rotor, but if the rotor does not absorb the heat properly, it can wear.

Each time you have your brake pads replaced, you should have the rotors inspected and measured to make sure they have enough metal left on them to help you brake safely. If rotors are not yet at the minimum thickness level, but they are getting close, they might be able to be resurfaced. Otherwise, they will need to be replaced.

New Rotors Vs Resurfacing 

Resurfacing

If you want to save yourself the cost of getting new rotors, sometimes resurfacing is a possibility. If you have taken notice of the wear on the rotors early enough, it is to your advantage. If they wear down too far, resurfacing will not be an option. They also cannot be resurfaced if they are cracked, rusted or grooved in any way.

New vs Resurfacing rotorsResurfacing a rotor removes metal and makes the rotor thinner, which reduces its overall service life. Some consumers do not want rotors resurfaced unless they are close to the point of no return. Resurfacing restores the flat, smooth, original surface of the rotor that allows you to get the proper friction between the rotors and the brake pads. This minimized noise in the brakes as well as vibration and it allows you to stop properly. Installing new brake pads on old rotors can cause the pads to wear faster and make less contact with the rotor, which may not slow the car down as much.

Replacing

Some car owners to prefer to simply replace their rotors instead of trying to resurface them. They do not cost all that much and they will last longer than resurfaced rotors. For customers who have rotors that are too used or for those who want optimum braking, new rotors are best.
