Specified brake fluid: DOT 4 EWB02720 ECB01160 WARNING Improper maintenance can result in loss of braking ability. Observe these precautions: G Insufficient brake fluid may allow air to enter the brake system, reducing braking performance. G Clean the filler cap before removing. Use only DOT 4 brake fluid from a sealed container. G Use only the specified brake fluid; otherwise, the rubber seals may deteriorate, causing leakage. G Refill with the same type of brake fluid. Adding a brake fluid other than DOT 4 may result in a harmful chemical reaction. G 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. NOTICE Brake fluid may damage painted surfaces or plastic parts. Always clean up spilled fluid immediately. 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 and/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. EBU24291 Changing the brake fluid Have a Yamaha dealer change the brake fluid at the intervals specified in the TIP after the periodic maintenance and lubrication chart. In addition, have the oil seals of the master cylinders and calipers as well as the brake hoses replaced at the intervals listed below or whenever they are damaged or leaking. G Oil seals: Replace every two years. G Brake hoses: Replace every four years. 8-49 8
