Brake
Inspect initially at 1 000 km (600 miles, 2 months) and every 6 000 km (4 000 miles, 12 months) thereafter.
Brake hose and brake fluid
Inspect every 6 000 km (4 000 miles, 12 months).
Replace hoses every 4 years. Replace fluid every 2 years.

Brake fluid level check
- Keep the motorcycle upright and place the handlebars straight.
- Check the brake fluid level relative to the lower limit lines on the front and rear brake fluid reservoirs.
- When the level is below the lower limit line, replenish with brake fluid that meets the following specification.
Specification and classification: DOT 4

Warning:
- The brake system of this motorcycle is filled with a glycol-based brake fluid. Do not use or mix different types of fluid such as silicone-based and petroleum-based fluids. Do not use any brake fluid taken from old, used or unsealed containers. Never re-use brake fluid left over from the last servicing or stored for a long period of time.
- Brake fluid, if it leaks, will interfere with safe running and immediately discolor painted surfaces. Check the brake hoses and hose joints for cracks and fluid leakage before riding.
Brake pads
Front brake
The extent of brake pad wear can be checked by observing the grooved limit line А on the pad. When the wear exceeds the grooved limit line, replace the pads with the new ones. (9-52)
Caution: Replace the brake pads as a set, otherwise braking performance will be adversely affected.

Rear brake
The extent of brake pad wear can be checked by observing the grooved limit line А on the pad. When the wear exceeds the grooved limit line, replace the pads with the new ones. (9-63)
Caution: Replace the brake pads as a set, otherwise braking performance will be adversely affected.

Brake pedal height
- Loosen the lock nut 1.
- Turn the push rod 2 until the brake pedal height becomes 25 - 35 mm (1.0 - 1.4 in) А below the top of the footrest.
- Tighten the lock nut 1 securely.

Rear brake master cylinder rod lock nut: 18 Nm (1.8 kgf·m, 13.0 lb·ft)
Brake pedal height А: Standard: 25 - 35 mm (1.0 - 1.4 in)

Brake light switch
- Adjust the rear brake light switch so that the brake light will come on just before pressure is felt when the brake pedal is depressed.

Air bleeding from brake fluid circuit
Air trapped in the brake fluid circuit acts like a cushion to absorb a large proportion of the pressure developed by the master cylinder and thus interferes with the full braking performance of the brake caliper. The presence of air is indicated by "sponginess" of the brake lever and also by lack of braking force. Considering the danger to which such trapped air exposes the machine and rider, it is essential that after remounting the brake and restoring the brake system to the normal condition, the brake fluid circuit be purged of air in the following manner.
Front brake
- Fill the master cylinder reservoir to the top of the inspection window. Replace the reservoir cap to prevent dirt from entering.
- Attach a hose to the air bleeder valve and insert the free end of the hose into a receptacle.
- Squeeze and release the brake lever several times in rapid succession and squeeze the lever fully without releasing it. Loosen the air bleeder valve by turning it a quarter of a turn so that the brake fluid runs into the receptacle. This will remove the tension of the brake lever causing it to touch the handlebar grip. Then, close the air bleeder valve, pump and squeeze the lever, and open the valve. Repeat this process until fluid flowing into the receptacle no longer contains air bubbles.

Note: While bleeding the brake system, replenish the brake fluid in the reservoir as necessary. Make sure that there is always some fluid visible in the reservoir.
- Close the air bleeder valve and disconnect the hose. Fill the reservoir with brake fluid to the top of the inspection window.
Air bleeder valve: 7.5 Nm (0.75 kgf·m, 5.5 lb·ft)
Caution: Handle brake fluid with care: the fluid reacts chemically with paint, plastics, rubber materials, etc.

Rear brake
- Bleed air from the rear brake system in the same manner as front brake.
Air bleeder valve: 7.5 Nim (0.75 kgf·m, 5.5 lb·ft)
Note: The only of between operation from bleeding the front brake is that the rear master cylinder is actuated by a pedal.
