1. A brake rotor assembly, comprising:
a structural part having a receiving surface aligned perpendicularly to an axis of rotation of the structural part, the structural part of the brake rotor comprised of a material not including stainless steel; and
at least two friction surface parts, each friction surface part having a contact surface, the at least two friction surface parts being comprised of stainless steel, the at least two friction surface parts fixably attached to the receiving surface of the structural part such that the contact surfaces face away from the receiving surface of the structural part to form at least part of an annular braking surface arranged concentrically around the axis of rotation, each of the structural parts, the at least two friction surface parts, the contact surfaces, and the receiving surfaces are positioned on the same plane, the at least two friction surface parts coated with a wear and corrosion resistant coating, the wear and resistant coating including a support layer, a first layer, and a second layer, the at least two friction surface parts arranged on the receiving surface to form the at least part of the annular braking surface;
the receiving surface having an upper portion and a lower portion, wherein the contact surface of the friction surface part is spaced apart from the upper portion of the receiving surface of the structural part.
