5. Replace the brake pads
●A qualified maintenance organization should check and
maintain the brake pads on a regular basis.
●Do not drive immediately after replacing the new brake
pads. Be sure to hold and release the brake handle several
times to allow the brake disc and brake pads to fully fit
together to restore normal grip and to make the brake fluid
circulate stably.
●The braking distance may be longer than the original
braking distance after replacing the new brake pads. It needs
to be used for about 300 kilometers (186 mile), and the best
braking effect can be achieved after the brake disc and the
brake pads are fully run-in. . Allow enough braking distance
before running in sufficiently to ensure driving safety.
●The brake pads must be replaced in pairs, only replacing
one side will cause uneven braking.
●The brake pads must be assembled correctly.
●Do not operate the brake handle after removing the brake
pads.
