The Zimmermann Coat-Z brake disc provides a protective coating that
prevents rust and corrosion, extended rotor life and improved visual
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.
Material quality / high carbon - 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
Heat treatment - Based on the latest developments in
the casting technology, the cooling process after moulding is controlled
in such a way that the tension relief is already guaranteed from the
foundry on. The cost-intensive glowing of the raw or semi-finished parts
(slow heating to the annealing temperature, maintaining this temperature
for several hours and then slowly re-cooling) can therefore be omitted
Features and Benefits:
OE-Equivalent and Direct fit Application.
High carbon content disc.
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
German production meeting the requirements of actual Quality
Well known, highest Otto-Zimmermann-Product-Quality
RUN IN NOTICE - The following run-in notices are
recommended to ensure a safe and proper operation of the brake disc /
brake pad system:
Violent or shock-braking should be avoided during the first 300 km of
travel after the change of the brake discs.
Through a moderate run-in, a gradual warming of the brake disc is
performed without creating a heat shock and the friction surfaces of
brake disc and brake pad are aligned to each other.
Perform at least 30 brake applications from a medium velocity (approx.
100 km/h) with a moderate deceleration (maximum braking time 3
seconds) down to a velocity of initially 50 km/h, and after about half
of the braking cycles were performed down to 25 km/h. Hereby letting
the brake disc cool down for approx. 3 min. between the brake cycles
through the motion airflow.
If these instructions are not complied with, Zimmermann shall not honor
any warranty claims, if this non-compliance causes damage to the product
or damages/harm to third parties. Furthermore, a warranty will also not
be provided if damages and/or defects occur that are attributable to
intensive use and/or individual driving behavior and/or were caused by
