Like many issues concerning brake rotors, different people have different opinions about what works best. So with that said, let's take a closer look at rotor refinishing and what it really takes to guarantee quiet brakes.

WHEN TO TURN ROTORS
By the time a vehicle needs new brake pads, the rotors may show considerable wear. The areas on the rotors where the pads rub will often have grooves, maybe some minor surface cracking or pitting, and possibly enough variations in thickness due to wear that are causing noticeable pedal vibrations when the brakes are applied.

Most shops resurface rotors every time they replace a set of pads. Some would argue that rotors in relatively good condition (only minor grooving and no hard spots, cracks or pedal pulsations), do not need to be resurfaced. Not resurfacing the rotors extends their life and saves the vehicle owner some money. Others say the risk of a comeback because the rotors were not resurfaced is reason enough to turn the rotors.
