Brake maintenance
In order to maintain your bicycle’s braking performance, it is important
to perform maintenance on the braking system at the intervals
described in the chapter entitled “regular maintenance and checks”:
• Replacing worn disk brakes or pads: the surface markings are no
longer visible or the metal structure is under 2mm from the rim or
from the disk.
• The position of mechanical disk brakes must be adjusted regularly as
they wear.
• Replacing brake cables and housings.
• Cleaning hydraulic brake circuits.
Maintaining Roller Brake brakes
The greasing of " Roller brake " type brakes should be checked every
year by a specialist. The type and quantity of grease affect braking
power.
The wear of " Roller brakes " is measured by a tool not sold with the bike
and available in store.
