.IX. Inspection and adjustment of the front brake
[Check] (Picture 22)
●Measure the free stroke of the front brake handle: 5～10mm.
●Measure the thickness of the front brake disc and brake friction lining.
●Check the oil level in the oil cup; check whether the brake caliper is normal; check
the brake oil pipe and
There is no oil leakage or cracks in the brake oil cup; check the wear of the brake
disc.
●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.
