Fig. 16 - Measuring brake pad wear
5. On both brake pads, measure the distance from
the back plate (A) to the wear surface (B) of the
brake pad in four places, see ► Fig. 16 . The min-
imum permitted pad thickness (friction material) is
2 mm.
Danger!
Failure to comply poses a risk of the pad back plate
becoming lost, which could endanger individuals.
The SAF guarantee of competence shall be made
void in the event of the minimum pad thickness not
being met and if damage results.
6. Check the condition of the back plate (A).
7. Replace the brake pads if they are worn out or if
they are expected to be so before the next inspec-
tion. For replacement follow the instructions in
chapter
„5.2 Replacing the brake pads“
.
8. Once the inspection is completed satisfactorily,
conclude by following chapters „5.2.3 Installing the
brake pads“ and „5.2.4 Final procedure“ .
Note:
This brake disc inspection check procedure is only
a general guide. Refer to the vehicle manufacturer's
documentation for specific brake disc information
and instructions.
4.3.4 General brake pad clearance check
Danger!
Wear respiratory protection in order to avoid inhaling
particles which can be hazardous to health! Brake
pad wear produces dust which can cause lung dam-
age!
Note:
● The clearance can be checked with the brake
chamber fitted or removed.
● This check is best performed after the wheel is
removed and before the reset shaft is retracted.
For this situation, steps 2 and 3 below can be
skipped.
1. Read and follow chapter „3.2 Initial procedure“ and
„5.2.2 Removing the brake pads“ prior to checking
the clearance.
2. Reduce the clearance by inserting and manually
rotating the Torx 55 socket clockwise until it comes
to a stop. The excessive clearance is hereby
rectified. Now set the correct clearance by rotating
270° anti-clockwise.
3. Activate the brake until the Torx 55 bolt no longer
rotates because any excessive clearance has
been removed by the adjustment function.
Fig. 17 - Correct location of the feeler gauges
4. Insert two feeler gauges in between the brake
calliper and the outer brake pad to measure the
clearance. Position the feeler gauges in the upper
and lower part of the brake pad back plate so that
the axial clearance can be measured, see ► Fig.
17 .
5. The normal clearance is between 0.7 mm and
1.1 mm. If the measurement is outside of the nor-
mal running condition then continue with chapter
„8.2 Inspection intervals“ .
