2.4.1 Brakes
Important comments and precautionary
measures:
Ask an approved O2feel reseller to carry out
maintenance work on brakes.
Do not use oily liquids on brake linings, surfaces
of wheel rim brakes, brake pads or disks. If you do,
this will hinder the performance of your brakes.
Only use original spare parts. Failure to do so runs
the risk of damaging or hindering the performance
of your bike.
To achieve good braking performance, only use
suitable brake linings for the rims. Failure to do so
may increase the braking distance and your brakes
will become worn more quickly.
Brake cables are subject to wear. Check them
regularly for wear and replace them if necessary.
Check to make sure the brake cable is not rusty or
frayed. Replace it if any defects are present. If it is
not replaced, the brakes might not work properly.
Standard brake lever:
The bike is fitted with appropriate standard brake
levers. Check them regularly to make sure they
work without hindering your ride.
Rim brakes
Get used to using V-Brake brakes and learn how
to adjust your braking power. Practise doing
emergency stops until you are in control of your
bike, including in difficult braking conditions.
Incorrect us of additional suspension elements in
the braking system (power regulators) may cause
serious falls. The required suspension power of
the power regulator depends on the total weight
of the bike.
When the brake pads are so worn that you can no
longer see the grooves, get them replaced by your
approved O2Feel reseller.
Adjusting the brakes
The brakes on your bike will have been adjusted
correctly when they left the factory or by your
reseller. The space between the brake pad and
the rim must be between around 1 and 1.5mm.
However, brake pads are subject to wear. The
space increases with use and the travel of the
brake lever gets longer and longer. For this reason,
you must check your brakes regularly and adjust
them when the travel of the brake lever is too
longer and the brake no longer works properly.
Follow these steps to check your brakes:
•
Press the brake lever for the front wheel hard,
then for the rear wheel, as you would do when
cycling in difficult braking conditions. Then push
your bike forwards.
•
The back wheel should not move.
•
The front wheel should slow down until the bike
starts to tilt forward.
Hydraulic disc brakes
Hydraulic disc brakes are fitted with a master
cylinder next to the manual brake lever. The
hydraulic fluid travels to the brake cylinders via a
brake line. The brake pads are pressed against the
disc by pistons. This type of brake is very powerful
and does not require much maintenance.
Whenever you adjust them, test the brakes by
pushing the bike firmly whilst applying the brake
lever. Only use your bike if it brakes safely.
Regularly check to make sure that the tubes and
outer casings are properly sealed, including every
time you go out. Tubes and fittings that are not
sealed properly may result in braking fluid leaks
and prevent the brakes from working properly.
If any fluid leaks from the braking system, stop
using the bike and get a specialist to carry out the
necessary repairs immediately.
If you cycle with the brakes in this state, there is a
significant risk of the brakes failing.
