4.12.1 Front disc brake pads: checking thick‐
ness
Note
One some vehicles it may be very difficult to ascertain or meas‐
ure the thickness of the pad due to the geometry of the wheel
rim. If this is the case, remove the wheel on the side where
the brake pad wear indicator is installed for better evaluation or
measurement of the remaining pad thickness.
Procedure
– Measure outer and inner brake pad thickness by inspecting
through the holes of wheel rim (depending on type).
– For better evaluation or measurement of remaining pad
thickness, remove wheel on side where brake pad wear indi‐
cator is installed as necessary.
– Pull off wheel bolt covers if necessary ⇒ page 49 .
– Mark position of wheel relative to brake disc.
– Unbolt wheel bolts and remove wheel.
– Measure inner and outer pad thickness.
