This behavior is specific to the stateof\-the\-art technology found in NAO pad material. The pad compound incorporates nonferrous metal, which can affect the appearance of the brake discs. Color transfer on friction surfaces: With heavy or extreme braking, color transfer to the disc from the pads is intensified and may generate dark spots or circular traces. Normal braking will gradually reduce the discoloration. This will not affect braking performance. No repair attempt is needed.
