PERIODIC MAINTENANCE

3-17

WARNING

EWA13070

After adjusting the brake pedal position, 
check that the end of the adjusting bolt “c” 
is visible through the hole “d”.

c. Tighten the locknut “1” to specification.

WARNING

EWA13050

A soft or spongy feeling in the brake lever 
can indicate the presence of air in the brake 
system. Before the vehicle is operated, the 
air must be removed by bleeding the brake 
system. Air in the brake system will consid-
erably reduce braking performance.

ECA13510

After adjusting the brake pedal position, 
make sure there is no brake drag.

3. Adjust:

• Rear brake light switch

Refer to “ADJUSTING THE REAR 
BRAKE LIGHT SWITCH” on page 3-33.

EAS21260

CHECKING THE REAR BRAKE PADS

The following procedure applies to all of the 
brake pads.
1. Operate the brake.
2. Check:

• Rear brake pad

Wear indicators “1” almost touch the 
brake disc 

→

 Replace the brake pads as 

a set.
Refer to “REAR BRAKE” on page 4-43.

BLEEDING THE HYDRAULIC BRAKE SYS-
TEM

WARNING

EWA13100

Bleed the hydraulic brake system when-
ever:
• the system is disassembled.
• a brake hose is loosened, disconnected 

or replaced.

• the brake fluid level is very low.
• brake operation is faulty.

TIP

• Be careful not to spill any brake fluid or allow 

the brake fluid reservoir to overflow.

• When bleeding the hydraulic brake system, 

make sure there is always enough brake fluid 
before applying the brake. Ignoring this pre-
caution could allow air to enter the hydraulic 
brake system, considerably lengthening the 
bleeding procedure.

• If bleeding is difficult, it may be necessary to 

let the brake fluid settle for a few hours. 
Repeat the bleeding procedure when the tiny 
bubbles in the hose have disappeared.

1. Bleed:

• Hydraulic brake system

▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼

a. Fill the brake fluid reservoir to the proper 

level with the recommended brake fluid.

b. Install the brake fluid reservoir diaphragm.
c. Connect a clear plastic hose “1” tightly to 

the bleed screw “2”.
