As spring nears, many drivers wonder if they should replace their rotors, or simply turn them? To address this question, there are a few basics to consider.
Technically speaking your brakes are an energy transfer device. They take the force of your vehicle and absorb it into the braking system, causing heat from the friction.
The bigger the "heat sync" or rotor, the better the chance of dispersing that energy and recovering in time to stop. The relationship between the pad and rotor is key in the strength and ability to dispense the heat for your brakes.
Will your car be affected if you choose to turn your rotors instead of replacing them? The answer depends on the manner in which you drive your vehicle. If you drive in a pedestrian manner and never push the limits of your car, turning your rotors would be allowed. If you push your vehicle's limits in a sporty manner, you may find yourself in a situation where your braking power is diminished and turning your rotors is not an option. However, rotors are inexpensive and can be changed for less than the cost of labor for turning.
