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.

7.5.2.1 Checking the hand brake

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,
6.5.9.5).
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
 Contact your specialist dealer if the pressure
point cannot be reached.
MY22H03 - 22_1.0_01.10.2021
Section 6.5.9.4 or Section
Section 6.5.9.8).

7.5.2.2 Checking the hydraulic system

1 Push the brake lever and check whether any
brake fluid leaks out of the lines, connections
or on the brake linings.
 If any brake fluid leaks from anywhere, take
pedelec out of service. Contact specialist
dealer.
2 Push brake lever and hold several times.
 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.
2 Check the physical condition of the Bowden
cables for visible damage and check to see if
wire strands are broken.
 Have defective Bowden cables replaced.
Contact specialist dealer.
