1. Brake adjustment

a. Front brake lever free play adjustment

The brake can be adjusted by simply adjusting the free play of the brake lever. The piston in the caliper moves forward as the brake pad wears out, automatically adjusting the clearance betweenthe brake pads and brake disc.

CAUTION:
Proper lever free play is essential to avoid excessive brake drag.

1. Adjuster 2. Lock nut a. 5 — 8 mm (0,2 ~ 0.3 in)

1)   Loosen the adjuster lock nut on the brake lever.

2)  Turn the adjuster so that the brake lever movement at the lever end is 5 ~ 8 mm {0.2 ~ 0.3 in) before the adjuster contacts the master cylinder piston.

3)  After adjusting, tighten the lock nut.

b. Rear brake pedal height adjustment


1)  Loosen the adjuster lock nut (for pedal height).

2)   By turning the adjuster bolt clockwise or counterclockwise, adjust the brake pedal position so that its top end is approximately 20 mm (0.78 in) below the foot rest top end.

3)  Secure the adjuster lock nut.

WARNING:
After adjusting the pedal height, the brake pedal free play should be adjusted.

1. Adjuster bolt            3. Footrest

(for pedal height)   4. Pedal height 20 mm (0.8 in)

2.  Lock nut                   5. Free play 20 — 30 mm (0.8—1.2 in)

c. Rear brake pedal free play adjustment

Turn the adjuster on the brake rod clockwise or counterclockwise to provide the brake pedal end with a free play of 20— 30 mm (0.8- 1.2 in).

NOTE:
Check to see whether or not the brake light operates correctly after adjusting.

2. Front brake pad and rear brake shoe check

a. Front brake pad

To check, look at the pad wear indicator in back of the caliper. If any pad is worn to the wear limit, replace both the pads in the caliper. Front

1. Wear indicator

b. Rear brake shoe

To check, see the wear indicator position while depressing the brake pedal. If the indicator reaches to the wear limit line, replace the shoes.

3. Brake fluid

Insufficient brake fluid may allow air to enter the brake system, possibly causing the brake to become ineffective. Check the brake fluid level and replenish when necessary observing these precautions:

1. Lower level

a. Use only the designated quality brake fluid; otherwise, the rubber seals may deteriorate, causing leakage and poor brake performance.

Recommended brake fluid: DOT#3

b.  Refill with the same type and brand of brake fluid; mixing fluids may result in a harmful chemical reaction and lead to poor performance.

c.   Be careful that water or other contamination does not enter the master cylinder when refilling. Water will significantly lower the boiling point and may result in vapor lock.

d.   Brake fluid may erode painted surfaces or plastic parts. Always clean up spilled fluid immediately.
