IMPORTANT
Disc brake systems, whether they are hydraulic or not, require a run-
in period before they reach optimal performance. It is possible that the
braking power is very weak during your first ride. We recommend that you
ride with great caution during this run-in period! Do not keep the brakes on
for long periods before you have completed the running in period, as this will
result in your brake pads glazing over, reducing their power and efficiency.
The running–in period will depend on the model and the climatic
conditions. As a general rule, the pads are run in after approximately 50
repetitions of braking from 30-0km/h. You can consider the brakes
completely run in when the braking power stops increasing with each run.
WARNING! Whether they are hydraulic or not, disc brakes are complex mechanical
systems that have a multitude of adjustments. So as to ride in complete safety and
be able to exploit their performance as much as possible, we suggest that you read
the brake manufacturers manual delivered with your bicycle.
WARNING! Disc brakes can reach a very high operating temperature. Do not touch
them, especially after a long descent, as you can burn yourself.
GENERAL INFO ON DISC BRAKES INSPECTING AND ADJUSTING CABLE DISC BRAKES
TIP! It is possible that a light rubbing can be heard when the wheel turns. This
sound comes from light contact between the disc and the brake pads, and will
disappear after the initial running-in period. If the wheel does not turn freely or
the sound does not disappear however, it would be best to seek professional help.
WARNING! The liquid contained in the hydraulic brake system is harmful for your
health. If your skin comes into contact with the liquid, clean it off with clear water
and consult your doctor. The liquid is also very corrosive on paint, clothing, etc, so
be very careful when handling it.
The air tightness of the hydraulic system is what guaranties the correct functioning
of the braking system. If there is a leak, even a tiny one, do not ride your bike.
Instead, take the bike to a professional mechanic so that they can check it out and
repair if necessary. Make sure that the brake liquid does not come into contact
with the brake pads or discs, as this would dangerously alter the efficiency of the
braking system.
1. Pull on the brake levers. At the end of their travel, they should not be in
contact with the handlebars.
2. Lift and spin the wheels. They should spin freely. If this is not the case,
you will need to adjust the brake caliper. This is a complex operation that
needs a lot of care. Contact your local retailer so that they can carry out the
operation.
3. Once the adjustments have been carried out, it is essential that you test
your brakes at a standstill to make sure that they work properly.
TIP! The hydraulic brake system has an automatically adjusting brake pad wear
system. Therefore do not pull on the brake levers when the wheels are not on the
bicycle! This will result in the pads sticking together, rendering the repositioning
of the wheels on the bicycle impossible.
