CHECKING BRAKE FLUID LEVEL

Make sure that a brake fluid level in reservoir tank is within the
standard (between MAX and MIN lines).

Visually check around reservoir tank for fluid leakage.

If the level is excessively low, check brake system for leakage.

Release parking brake pedal and see if brake warning lamp
goes off. If not, check brake system for fluid leakage.
Checking Brake LineNFS000RW
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Drain and RefillNFS000RX
CAUTION:

Refill with new brake fluid “DOT 3”.

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.

Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
