At regular intervals, check that the brake
pads and discs are free from grease, oil or
other contamination. In addition, check the
thickness of the brake disc. The minimum
thickness is printed on the brake disc. In
addition, the brake pad thickness must be
checked with a measuring calliper. The
minimum pad thickness plus support material
is 2.5 mm.
In the event of abrupt, hard braking, there
is a risk that you might fall forward with your
upper body. Slowing down should be done
very carefully.
