Brake system
CAUTION
!
Crash caused by brake failure
Worn brake discs and brake linings, as well as a
lack of hydraulic fluid in the brake cable, reduce
the braking power. This may cause a crash with
injuries.
Check the brake disc, brake linings and the
hydraulic brake system on a regular basis and
replace if necessary.
The maintenance interval for the brake depends on
the weather conditions and how frequent the
pedelec is used. If the pedelec is used under
extreme conditions such as rain, dirt or high
mileage, maintenance must be performed more
frequently.
7.4.6
Checking the brake linings for wear
Check brake linings after brake has been fully
applied 1,000 times.
Check that the brake linings are no less than
1.8 mm wide at any point and no less than
2.5 mm between the brake lining and
supporting plate.
Push brake lever and hold. In doing so, check
the transport safety wear gauge can fit
between the brake lining supporting plates.
The brake linings have not reached their wear
limit. If they have, a specialist dealer will need
to replace the brake linings.
7.4.7
Checking the pressure point
Push brake lever and hold several times.
If you are unable to clearly detect the pressure
point and it changes, a ZEG specialist dealer
needs to vent the brake.
