EBU00755 Brake fluid level inspection Insufficient brake fluid may let air enter the brake system, possibly causing the brakes to become ineffective. Before riding, check that the brake fluid is above the lower level and replenish when necessary. Observe these precautions: 1. When checking the fluid level, make sure the top of the master cylinder is level by turning the handlebars. 2. Use only the designated quality brake fluid. Otherwise, the rubber seals may deteriorate, causing leakage and poor brake performance. Recommended brake fluid: DOT 4 FRONT 1. Minimum level mark "LOWER" 3. Refill with the same type of brake fluid. Mixing fluids may result in a harmful chemical reaction and lead to poor brake performance. 4. Be careful that water does not enter the master cylinder when refilling. Water will significantly lower the boiling point of the fluid and may result in vapor lock. 8-22
