PERIODIC MAINTENANCE AND MINOR REPAIR Front brake Clutch Rear brake 1. Minimum level mark EAU04169 1. Minimum level mark 1. Panel B 2. Minimum level mark G Checking the brake and clutch fluid levels 6 Insufficient brake fluid may allow air to enter the brake or clutch systems, possibly causing them to become ineffective. Before riding, check that the brake fluid is above the minimum level mark and replenish if necessary. A low brake fluid level may indicate worn brake pads and/or brake system leakage. If the brake level is low, be sure to check the brake pads for wear and the brake system for leakage. NOTE: The rear brake fluid reservoir is located behind panel B. (See page 6-9 for panel removal and installation procedures.) _ _ Observe these precautions: G When checking the fluid level, make sure that the top of the brake or clutch fluid reservoir is level. G Use only the recommended quality brake fluid, otherwise the rubber seals may deteriorate, causing leakage and poor braking or clutch performance. Recommended brake and clutch fluid: DOT 4 brake fluid 6-29 Refill with the same type of brake fluid. Mixing fluids may result in a harmful chemical reaction and lead to poor braking or clutch performance. G The brake or clutch fluid reservoir diaphragm will lose its shape from the negative pressure if the fluid level goes down too far. Be sure to return the diaphragm to its original shape before installing it into the brake or clutch fluid reservoir. G Be careful that water does not enter the brake or clutch fluid reservoir when refilling. Water will significantly lower the boiling point of the fluid and may result in vapor lock.
