2. Connect the wiring with miniature lamp (1) and a battery (2)
between valve bracket (3) and linkage (4) with each end of
wiring clipped.
This wiring is necessary to find the moment at which piston
within the valve assembly is brought into connect with the
linkage.
Note:
As the linkage is coated with insulation material, turn the
clip (5) with 2 or 3 turns to break insulation.
3. Loosen the nut (6) and raise the valve assembly (7) all the
way.
Then lower the valve assembly gradually and tighten the nut
(6) when miniature lamp (1) turns on.

Note:
If the miniature lamp (1) goes out as the nut (6) is
tightened, lower the valve assembly (7) slightly with the
nut loosened, then retighten the nut(6).
4. Depress the linkage (4) near the valve assembly slightly
downward with finger (test pressue:0.5-0.8kg) and check to
see if the miniature lamp (1) goes out.
Lamp goes out : OK Adjustment is completed.
Lamp remains on : NG Repeat adjustment operation
outline under paragraph 3.
Excessive force is exerted on
linkage by piston (8) within the
valve assembly.
Note:
Adjustment can also be made by means of nuts (9) and
(10) on shackle at rear axle case side.
However, shackle nut is not normally used for adjustment
as it is for making fine adjustment.

BRAKES 5-25
Floor mount type
All brakes are self-adjusting.
Brakes are adjusted by repeated stepping on the brake pedal.
(After stepping on the pedal and releasing it, the rear auto-
adjuster, in the rear brake, produces a clicking sound.
the same operation should be repeated until the sound
disappears.)
Take the following steps after overhauling the rear brake
assembly.
1. Move the parking brake lever to its fully released position.
2. Parking cable must be loosened sufficiently.
(Loosen the adjust nut and the lock nut.)
3. Repeat stepping on the brake pedal firmly, and releasing it
until the clicking sound can no longer be heard.
If the difference between the brake drum inside diameter of
the brake shoes is adjusted to be 0.5 mm, the number of
times for depressing the brake pedal can be reduced.
4. Remove the drum.
Measure the brake drum inside diameter and diameter and
diameter of the brake shoes.
Shoe Clearance mm(in)
0.25 - 0.40 (0.0098 - 0.0157)
If incorrect, check the brake auto-adjusting system.
5. Turn the equalizer nut so that the parking brake lever
travels 6 or 7 notches when pulled up with a force 30 kg (66
lbs.).
6. Make sure there is not brake dragging and tighten the cable
lock nut.
