braking. Thiswilldepend on:
R Speed
R Braking force
R Ambient condition s,e.g. temperature and
humidity
The wear ofindividual componen tsof the
brake system, suchasthe brake pads/linings
or brake discs, depends onthe individual driv-
ing style andoperating conditions.
For this reason, itis impossible tostate amile-

An aggressive drivingstylewilllead tohigh
wear. Youcanobtain moreinformation onthis
from aqualified specialist workshop.
New andreplaced brakepadsanddiscs only
