10. Adjust the clearance between the brake drum and brake shoe.
Poke the adjusting hole plug on the brake drum, insert the screwdriver
into the clearance-adjusting hole; rotate the clearance-adjusting gear
to expand the brake shoe until the brake disc can not be rotated by
hand. Then rotate it for 3-5 teeth in anticlockwise, rotate the brake
disc by hand at the same time, it is proper that it can rotate freely
and without the contact between the abrasion and disc. It is allowable
that the non-running-in brake shoe has the slight abrasion sensing.
When adjust the clearance, the left and right wheel must be adjust at
the same, install the adjusting hole plug after the completion of
adjusting .

Table 1 SRS-ECU stitch description
5. The maintenance operation must be started after 60 seconds following the removal of negative connection of
accumulator, wrap the negative with insulating tape for insulation.
Due to the capacitance in SRS-ECU to maintain certain power to make the safety airbag release within a certain time after the
power-off of accumulator, the operation must be started after a while to avoid any possible major damaging accident caused
by the safety airbag’s improper release.
6. The parts such as SRS-ECU, safety airbag module as well as clock spring should be removed off and well preserved
providing the temperature is high enough to cause any damage(above93¡æ) in the painting operation.
The failure codes must be debugged with the diagnostic scanner following the repairing of SRS safety airbag system so as to
make alarm lamp work functionally.
