Front 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
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. Wa-
ter will significantly lower the boiling
point of the fluid and may result in va-
por lock.
