lining thickness of 3mm. Always replace pads as an axle set.
• At intervals of 100,000 kms, or every 6 months, (preferably

any accumulations of wear debris and rust from the edge of the
rotor, and from the pad location points in the caliper. Check also
condition and location of sealing boots.
NOTE

under normal operating conditions. Unusual ambient temperatures
or adverse operating conditions (e.g. dusty atmospheres or severe
gradients) will require more frequent service intervals. It is the
responsibility of the vehicle operator to establish these intervals.
