Checking the brake fluid level
Before riding, check that the brake fluid is above the minimum level mark.
Make sure the reservoir is level with the ground when checking the fluid level.
- Specified brake fluid:
- DOT 4
Brake fluid may damage painted surfaces or plastic parts. Always clean up spilled fluid immediately.
Front brake
- Minimum level mark
Rear brake
- Minimum level mark
As the brake pads wear, it is normal for the brake fluid level to gradually go down.
- A low brake fluid level may indicate worn brake pads or brake system leakage; therefore, be sure to check the brake pads for wear and the brake system for leakage.
- If the brake fluid level goes down suddenly, have a Yamaha dealer check the cause before further riding.
Improper maintenance can result in loss of braking ability. Observe these precautions:
- Insufficient brake fluid may allow air to enter the brake system, reducing braking performance.
- Clean the filler cap before removing. Use only DOT 4 brake fluid from a sealed container.
- Use only the specified brake fluid; otherwise, the rubber seals may deteriorate, causing leakage.
- Refill with the same type of brake fluid. Adding a brake fluid other than DOT 4 may result in a harmful chemical reaction.
- Be careful that water does not enter the brake fluid reservoir when refilling. Water will significantly lower the boiling point of the fluid and may result in vapor lock.
