FUNCTIONAL AND VISUAL CHECK
5.1.4 - Exaggerated wear difference between inner and outer brake pads
5.1.5 - Exaggerated tangential oblique wear of brake pads

Exaggerated wear difference between inner and outer
brake pads
5.1.4 The total thickness of the friction material of the inner
and outer pad should be equal. If the difference between the
two pads is greater then
3.5 mm
(see Fig.), then the following
checks are necessary:
- Bearing clearance check (see Section. 5.3 and 5.4)
- Free movement of the brake pads in the caliper
(see
Section. 5.2)
- Possible collision with other parts on the axle or
vehicle body
- Excessive dirt and grime present, if necessary
contact the vehicle manufacturer
- piping of the compressed air line
Example:
a)
E=19 mm
F=15 mm >
NOT OK
b)
E=11,5 mm
F=13 mm >
OK
Exaggerated tangential oblique wear of brake pads
5.1.5 The total thickness of the friction material at either
end of the pad should be equal. If the difference between the
two ends is greater than
2 mm
(see Fig.), then the following
checks are necessary:
- Bearing clearance check (see Section. 5.3 and 5.4)
- Free movement of the brake pads in the caliper
(see
Section. 5.2)
- Possible collision with other parts on the axle or
vehicle body
- Excessive dirt and grime present, if necessary
contact the vehicle manufacturer
- Piping of the compressed air line
In addition the brake pads must be replaced (see Section 6).
Example:
1)
G=21 mm
H=18 mm >
NOT OK
2)
G=18 mm
H=19 mm >
OK
