●When operating the brake handle, if you feel that the handle pressure is insufficient, then there is air in the brake system;
the air in the brake system should be completely discharged before normal use; otherwise it will reduce the braking
performance or brake failure. This work should be completed at the designated dealership.
Warning:
1. It should be added: non-petroleum-based brake oil of DOT3 or DOT4; different brands cannot be mixed;
2. Brake oil is highly corrosive, do not splash on the surface of painted or plastic parts; if you drink it by mistake, you
should force it to spit out; if it gets on your eyes or skin, you should rinse it with plenty of water immediately and
consult a doctor;
3. Hydraulic disc brakes work under high pressure. In order to ensure safety and reliability, the replacement time of
brake friction pads and brake oil should not exceed the maintenance period;
4. When the hydraulic disc brake system needs to be repaired, it can only be repaired by professional technicians.
Note:
The brake is an extremely important component to ensure the personal safety of the rider, and the brake should be
checked and adjusted frequently.
Replace with a new brake disc or brake friction pad, and do not drive immediately; you should first manipulate (hold
and release) the front brake handle several times until the brake disc and the brake caliper mesh well.
