Check fluid level in reservoir tank. It should be between MAX
and MIN lines on reservoir tank.

●

If fluid level is extremely low, check brake system.

●

If the brake warning lamp comes on, check brake fluid level
switch and parking brake switch.

Checking Brake Line

EFS003FE

CAUTION:

If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.

1.

Check brake lines (tubes and hoses) for cracks, deterioration
and other damage. Replace any damaged parts.

2.

Check for oil leakage by fully depressing brake pedal while
engine is running.

Changing Brake Fluid

EFS003FF

CAUTION:

●

Refill with new brake fluid “DOT 3”.

●

Always keep fluid level higher than minimum line on reser-

cause paint damage. If brake fluid is splashed on painted
areas, wash it away with water immediately.

1.

Clean inside of reservoir tank, and refill with new brake fluid.

2.

Connect a vinyl tube to each air bleeder valve.

3.

Drain brake fluid from each air bleeder valve by depressing
brake pedal.

4.

Refill until brake fluid comes out of each air bleeder valve.
Use same procedure as in bleeding hydraulic system to refill brake fluid.
