6-27PERIODIC MAINTENANCE AND MINOR REPAIR123456789Observe these precautions:8 When checking the fluid level,make sure that the top of thebrake fluid reservoir is level.8 Use only the recommended qual-ity brake fluid, otherwise the rub-ber seals may deteriorate, caus-ing leakage and poor brakingperformance.8 Refill with the same type of brakefluid. Mixing fluids may result in aharmful chemical reaction andlead to poor braking perfor-mance.8 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.8 Brake fluid may deteriorate paint-ed surfaces or plastic parts.Always clean up spilled fluidimmediately.8 As the brake pads wear, it is nor-mal for the brake fluid level togradually go down. However, ifthe brake fluid level goes downsuddenly, have a Yamaha dealercheck the cause.Recommended brake fluid:DOT 4EAU03985Changing the brake fluidHave a Yamaha dealer change thebrake fluid at the intervals specified inthe NOTE after the periodic mainte-nance and lubrication chart. In addi-tion, have the oil seals of the brakemaster cylinder and caliper as well asthe brake hose replaced at the inter-vals listed below or whenever theyare damaged or leaking.8 Oil seals: Replace every twoyears.8 Brake hose: Replace every fouryears.
