What Is Rotor Seasoning?According to Baer Brake Systems, disc brake rotor seasoning is a vital first step with new rotors. Think of it like you would the molding of a babys personality because you will certainly be stuck with the results if you dont handle it properly. Seasoning new rotors is important because it molds the molecular structure of the iron/steel. When we properly season new rotors, were burning the factory machine oils off of the surface and establishing a pad/rotor marriage.
The most complex break-in task is relieving the internal stresses within the iron/steel. If this is hard to understand, think of it like you would pouring water into a glass of ice. The casting and cooling of the iron leaves the material with internal stresses you dont need. How to relieve stress? Heres what Baer suggests.
