7.5.2 Checking the brake system
CAUTION
!
Crash caused by brake failure
Worn brake discs and brake linings and a lack of
hydraulic fluid in the brake line reduce the braking
power. This may cause a crash with serious
injuries.
 Check brake disc, brake linings and the
hydraulic brake system regularly. Contact
specialist dealer.
The maintenance interval for the brake depends
on how often it is used and the weather
conditions. If the pedelec is used under extreme
conditions such as rain, dirt or high mileage,
maintenance must be performed more frequently.

1 Check whether all screws in the handbrake are
firmly in place.
 Tighten loose screws.
2 Check whether the brake lever is torsionally
rigid on the handlebars.
 Tighten loose screws.
3 Check that there is a gap of at least 1 cm
between the handbrake lever and the handle
when the brake lever is fully applied.
 Adjust the grip distance if the gap is too narrow
(see Section 6.5.9.6,
6.5.9.8).
4 Check the braking effect by pedalling while
pulling the brake lever.
 If the braking power is too weak, adjust the
brake pressure point (see

 If any brake fluid leaks from anywhere, take
pedelec out of service. Contact specialist
dealer.

 If you are unable to clearly detect the pressure
point and it changes, the brake needs to be
bled. Contact specialist dealer.
7.5.2.3 Checking the Bowden cables
1 Pull on the brake lever several times. Check
whether the Bowden cables get stuck or they
make scraping noises.
