Checking the brake system

CAUTION
!
Crash caused by brake failure
Worn brake rotors and brake pads and a lack
of hydraulic fluid in the brake line reduce the
braking power. This may cause a crash with
serious injuries.
 Check brake rotor, brake pads 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 ebike 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,
6.5.10.2).
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.
Section 6.5.10.1 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 pads.
 If any brake fluid leaks from anywhere, take
ebike 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 brake cables
1 Pull on the brake lever several times. Check
whether the cables get stuck or they make
scraping noises.
2 Check the physical condition of the
cables for visible damage and check to see if
wire strands are broken.

specialist dealer.
