The Zimmermann Coat-Z brake disc provides a protective coating that prevents rust and corrosion, extended rotor life and improved visual appearance. To improve the rust protection during storage and usage, Otto Zimmermann GmbH implements this new Coat-Z technology step by step in its production range. Beside the still optimum function of the brake disc, this coating ensures a consistent attractive appearance.
Zimmermann brake discs are usually made of cast iron (with flake graphite) of different qualities; they correspond to the material used for the original spare parts. Therefore, the utilization of such materials (referred to as High Carbon by the competition) has always been a matter of course for Otto Zimmermann.
Features and Benefits:
Coat-Z protective anti-corrosion coating
No formation of rust at the hub and herewith improved visual appearance
Immediate functional capability without removal of the coating before mounting
Excellent deceleration action and no distortion of friction ring at high temperatures
Substantial weight saving and therefore less unsprung mass
Floating mounting enables radial expansion of the brake disc under relatively heavy loads, thus preventing shielding and increasing resistance to heat cracks
Hot spots prevented by optimized design of ventilation channels
