If the parking brake lever stroke is not the standard value,
adjust as described below.
(1) Loosen the adjusting nut at the floor console to release
the cable.
(2) Remove the adjustment hole plug, and then use a flat-tip

the arrow (the direction which expands the shoe) until
the disc cannot be rotated by both hands.
Return the adjuster five notches in the direction opposite
to the direction of the arrow. (Reference: shoe clearance
on one side 0.19 mm)
(3) Turn the adjusting nut to adjust the parking brake lever
stroke to the standard value. After adjusting, check that
there is no space between the adjusting nut and the

value and the braking is too firm, the rear brakes
may drag.

2. Set the vehicle onto a speedometer tester and use wheel
chocks to hold the rear wheels.
3. Pull the parking brake lever firmly.
4. To prevent the front wheel from moving from side to side,
attach tension bars to the tie-down hook, and secure
both ends to anchor plates.
5. To prevent the vehicles from starting, attach a chain or
wire to the rear towing hook, and secure the other end
of the chain or wire firmly to an unmovable body.
6. Check if the speedometer indication range is within the
standard values and if the pointer fluctuation is within
the limits.
Caution
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.
