Periodic maintenance and adjustment6-226 A low brake fluid level may indi-cate worn brake pads or brakesystem leakage; therefore, be sureto check the brake pads for wearand the brake system for leakage. If the brake fluid level goes downsuddenly, have a Yamaha dealercheck the cause before further rid-ing.WARNINGEWA15991Improper maintenance can result inloss of braking ability. Observethese precautions: Insufficient brake fluid may al-low air to enter the brake sys-tem, reducing brakingperformance. Clean the filler cap before re-moving. Use only DOT 4 brakefluid from a sealed container. Use only the specified brake flu-id; otherwise, the rubber sealsmay deteriorate, causing leak-age. Refill with the same type ofbrake fluid. Adding a brake fluidother than DOT 4 may result in aharmful chemical reaction. Be careful that water does notenter the brake fluid reservoirwhen refilling. Water will signifi-cantly lower the boiling point ofthe fluid and may result in vaporlock.EAU22734Changing the brake fluidHave a Yamaha dealer change thebrake fluid every 2 years.
