Brakes

As it is a hydraulic braking system, your maintenance options are limited. Work on
the hydraulics should be carried out by HNF-NICOLAI Service or a specialist work-
shop. In any case, please contact HNF-NICOLAI Service if the pressure point of the
brakes fluctuates.

6.8.1. Brake pad and brake disc wear

Brake pads and brake discs are subject to functional wear caused by friction between
the two parts. The wear depends on the riding style, terrain, weather and ground
conditions, meaning that no binding information can be given regarding the brake pads.
Brake discs need to be replaced after approx. 4 to 5 changes of brake pad pairs,
as they are made of a harder material. It is recommended to check the brake pads
every 500 km.

6.8.2. Checking the brake pads

The brake pads must be replaced when they
• are only 2.5 mm thick (height of carrier plate and friction lining)
• come into contact with oil (leads to low braking power)
To check the brake pad thickness, use the yellow transport lock supplied:
• Pull the brake lever and insert the rear side of
the transport lock between the carrier plates
of the corresponding brake calliper. If the
transport lock still fits between the pads, they
are not worn out.
• Alternatively, you can put the removed pads
into the small notch in the transport lock.
The pads are worn out when they fit into
the notch.
