Brake Discs

Brake Discs: The E65/E66 is equipped with vented brake discs on the front and rear axle made of high carbon cast iron. The brake disc surfaces are coated with Geomet to satisfy the increased corrosion protection requirements as well as the European directive for chromium free components (enforced from 7/2003 on).

Geomet is a zinc-aluminum surface coating (microfine scaled surface pattern) that is sprayed on and baked at 300 °C. It is environmentally compatible and features outstanding corrosion protection properties. On the friction surface of the discs, the protective coating is worn down without any changes in the coefficient of friction. All other surfaces retain the corrosion resistant coating over the entire service life.


NOTE: An initial scraping sound is normal and will disappear after the first few braking applications.
