Wear Areas On Brake Disc Friction Surface
As the pressure force of a brake piston on the brake pad varies in magnitude, different areas of wear arise on the friction surface.
The brake disc can basically be divided into the inner/outer and central wear area:
The central wear area -B- is the area with the highest degree of wear.
