Check Brake Pads
Note:
Check the brake pad thickness at regular intervals and depending on
the vehicle operation, during service intervals and in accordance with the
statutory provisions. Burned, glazed or oily brake pads must be replaced
immediately.
Always replace all the brake pads on the same axle at the same
time!
Caution: In order to avoid damage to the brake disc, the brake pads must
be replaced at the latest when a brake pad thickness of 2 mm over the
brake pad carrier plate is measured at the thinnest point.
The remaining pad thickness must not be less than 2 mm.
A
= Remaining pad thickness 2 mm.
B
= Total pad thickness 21 mm.
When the remaining pad thickness
A
<
2 mm
, replace the brake pads
as described in section 4.5.
Wear Measurement
The mean brake pad wear can be checked using a rollmeter or ruler,
depending on the accessibility, either at the fitting pin (long pin at the
leading end of the pad) or at the clearance pin (short pin at the trailing
end of the pad).
Measure the distance between the axle flange and the edge of the
brake calliper of the respective guide pin (arrows).
The wear limit is reached or exceeded at the following values:
Short guide pin: Wear limit > 73 mm
Replace brake pads
Long guide pin: Wear limit > 98 mm
Replace brake pads
4.4 Check Brake Disc
Remove the brake pads as described in section 4.5 and measure the
brake disc thickness in the brake pad contact area.
C
= Total thickness of new brake disc 45 mm
D
=
Wear limit 37 mm, the brake disc must be replaced.
Replacement of both discs on the axle is recommended.
E
= Total thickness of new brake pad 32 mm
F
= Brake pad carrier plate 9 mm
G
= Minimum thickness of brake pad 2 mm
H
=
Absolute minimum thickness of brake pad and pad carrier
plate 11 mm, the brake pads must be replaced.
Caution: Observe the wear limits of the brake pads and brake discs!
Worn brake pads and brake discs reduce the braking efficiency and
can even lead to failure of the brakes!
Risk of accidents!
