Checking the
brake pads
•
Check the thickness of the brake pads on all axle lines.
Each brake caliper ( 1 ) carries two brake pads ( 2 ), arranged one to the left
and one to the right of the brake disc ( 3 ).
The first and second axle lines have two brake calipers per brake disc.
The third and fourth axle lines have one brake caliper per brake disc.

Measure the pad thickness ( A ).
New brake pads have a pad thickness of
approx. 23 mm (0.90 in).
You must have the brake pads replaced if
– the brake pad thickness is less than 2 mm
(0.08 in) or
– the brake pads are burnt, glazed, broken or
oily;

There is a risk of damage if an unsuitable tool is used
The use of an unsuitable tool can damage the hexagon head of the
adjustment mechanism. An unsuitable tool can slip off the hexagon head
or can become jammed.
Always use a ring spanner, never an open end wrench.
When you apply the brakes the ring spanner on the hexagon head will
rotate with it. Therefore check in advance that there is sufficient clearance
for this rotational movement.
