5C-30 BRAKES
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 o
f
the brake shoes is adjusted to be 0.5 mm (0.020 in), the
number of times for depressing the brake pedal can be
reduced.
4. Remove the drum.
Measure the brake drum inside diameter and diameter o
f
the brake shoes.
Shoe Clearance mm (in)
0.25 - 0.40 (0.010 - 0.016)
If incorrect, check the brake auto-adjusting system.

5. Turn the adjuster nut so that the parking brake lever travels
7 notches when pulled up with a force 294N (30 kg / 66 lb).
6. Make sure there is no brake dragging.

ADJUSTMENT PROCEDURE OF BRAKE PEDAL
The push rod serves as the brake pedal stopper when the
pedal is fully released.
Brake pedal height adjustment should be performed as follows.
RTW 35CSH000601
Brake Pedal - Height
Measure the brake pedal height after making sure the pedal is
fully returned by the pedal return spring.
Note:
Pedal height (L2) must be measured after starting the
engine and increasing the revolution several times by
stepping on the accelerator pedal. mm (in)
Pedal free play (L1) 6 - 10 (0.24 - 0.39)
M/T 174 - 186 (6.85 - 7.32) Height (L2)
A/T 176 - 188 (6.93 - 7.40)
Note:
Pedal free play must be measured after turning off the
engine and stepping on the brake pedal firmly five times
or more.
If the measured value deviates from the above range, adjust
the brake pedal as follows:
a) Disconnect the stop lamp switch.
b) Loosen the lock nut on the push rod.
c)
Adjust the brake pedal to the specified height by rotating the
push rod in the appropriate direction.

How to connect the CLEVICE of the BOOSTER ROD with the
PEDAL ARM and how to adjust the PEDAL SW .
After connecting the CLEVIS of the BOOSTER ROD to the
PEDAL ARM, adjust the PEDAL SW mounted (PDA) to the
PEDAL BRACKET using the procedure explained below.
1. Set the hole of the CLEVIS of the BOOSTER & M/CYL
ROD with the hole in the PEDAL ARM.
2. Enter the PIN; PUSH ROD to the PEDAL to the holes from the left side of the PEDAL.
3. Enter and fix the PIN; SNAP PIN FIX to the DITCH o
f
the PIN; PUSH ROD to PEDAL from right side of the
PEDAL.

5. Pull the PEDAL ARM a little towards you so that the
PEDAL ARM is not pushed in.
6. Holding the PEDAL ARM still with one hand, push in the whole SW ITCH with the other hand until the PLUNGER
of the SW ITCH is pushed in and the SW ITCH itself hits
the RUBBER of the PEDAL ARM.
In this condition, turn the SW ITCH clock-wise until a “click” sound is heard and lock it.
By doing this the SW ITCH is adjusted at 0.7 ±0.5 mm
(0.028 ± 0.020 in) clearance.
