Different types of brakes have different braking capacities. If you are not happy or comfortable with your brake
system, consult a specialized repair shop, or get in touch directly with

With any brake system, an error in adjusting, maintaining or using the brakes can cause you to lose control of
the scooter.
If you are not sure about the brakes settings or you think there may be a problem, do not use the
scooter and take it to a specialized repair shop.
Hydraulic disk brakes
This brake system comprises: brake lever/brake fluid reservoir; hydraulic pipe; disk brake body/disk
brake pad; disk brake disk.
CHECKS TO BE MADE:
Before using the scooter squeeze the brake levers hard. The lever should not touch
the handlebar. If it does, the brake system should be bled. The job requires specialist equipment and knowledge
and should be carried out by a specialized repair shop.
Check that there is no oil, grease or any other type of dirty on the disk.
Check the disk brakes for signs of wear once a month. If the pads are less than 1mm thick they should be
replaced. You should also check that the pads are in the correct position, at a distance of between 0.25 and
0.75 mm from the disk when the brakes are not being applied.
Check that the pipe is not twisted or leaking. Replace any faulty parts in the system. Replacing parts requires
