Checking the brake system
•
Perform a brake test when at a standstill before every ride. To do so, pull each
brake lever towards the handlebar with normal braking force. The brake lever
must not touch the handlebar grip.
•
Move the vehicle back and forth with the brake applied. There must be no
significant play. If there is, get to the rootcause: The calliper or brake disc may
not be tightened. Tighten them to the torque values in the torque table in
section 9.3.
•
For hydraulic disc brakes, the pressure point on the brake lever must be stable.
If the pressure point is not reached after two-thirds of the lever stroke, pull
the lever several times in succession ("pumping"). Check if the pressure point
stiffens. In this case and if the location of the pressure point moves while
riding, the brake system must be bled by HNF-NICOLAI Service or by a qualified
specialist workshop.
•
The brake discs must be free of oil. If you find oil on the brake discs, remove it
with an alcohol-soaked cloth.
The pressure point is defined as the position of the lever stroke at which the
brake responds. If the brake works perfectly – i.e. there are no air bubbles
in the hydraulic line – the pressure point will be the same lever position for
each braking process.
Do not touch the brake discs with your hands. The thin film of oil on your
skin transfers to the brake discs and impairs their function.

Checking the belt
The Gates Carbon Drive is a maintenance-free, durable system. Nevertheless, the
following points must be considered:
•
Are there any foreign objects (e.g. twigs) between the pulley and belt? -> If yes:
Remove them.
•
Is the belt heavily soiled? -> If yes: Rinse it clean with water.

Battery: Checking the attachment and charge level
Check whether the battery is firmly in place in the lock and assess whether the charge
level is sufficient for your planned trip.
