Checking the brake fluid level

1

LOWER MIN

ZAUM00**

1. Minimum level mark

Insufficient brake fluid may allow air to enter the brake system, possibly causing it 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 fluid level is low, be sure to check the brake pads for wear and the brake system for leakage.

Observe these precautions:

8When checking the fluid level, make sure that the top of the master cylinder is level by turning the handlebars.

Use only the recommended quality brake fluid, otherwise the rubber seals may deteriorate, causing leakage and poor braking perfor- mance.

Recommended brake fluid:DOT 4

8Refill with the same type of brake fluid. Mixing fluids may result in a harmful chemical reaction and lead to poor braking performance.

8Be careful that water does not en- ter the master cylinder when refill- ing.Water will significantly lower the boiling point of the fluid and may result in vapor lock.

8Brake fluid may deteriorate painted surfaces or plastic parts. Always clean up spilled fluid immediately.

8As the brake pads wear, it is nor- mal for the brake fluid level to gradually go down. However, if the

brake fluid level goes down sud- denly, have aYamaha dealer check the cause.
