Why Should I Turn Rotors
Thursday, March 27, 2014 | Labels: i, rotors, should, turn, why | |
Turning a brake rotor is a process in which a machinist smoothes the surfaces of the rotor that is contacted by the brake pads. Consumers should understand when a brake rotor can and cannot be turned, as well as the advantages of turning the rotors.
When Rotors Cant Be Turned
Brake rotors should only be turned when the rotor can be smoothed but stay within manufacturers specifications. Most brake rotors will have the minimum thickness measurement stamped into the rotor. The information is also available in service manuals. Rotors with deep cracks should be replaced and not turned.
When Rotors Need Turning
Rotors do not need to be turned on a regular basis, but only when the rotor is showing signs of damage. Brake pads that were not replaced in a timely manner may cut deep grooves into the surface of a rotor. The rotor may also wear unevenly, resulting in a wavy surface. Brake rotors may also corrode, leaving the surface rough. All of these problems can be corrected by turning a rotor.
Advantages of Turned Rotors
The primary reason to turn rotors is to save money, as turning a rotor is less expensive than replacing it. Properly turned rotors will have a smooth surface that will improve braking distance, reduce brake noise and vibration, and increase brake pad life.
