On-Board Inspection NFS000OU
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 LineNFS000OV
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 RefillNFS000OW
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.
1. Connect a vinyl tube to bleed valve.
2. Depress brake pedal, loosen bleed valve, and gradually remove
brake fluid.

3. Make sure there is no foreign material in the reservoir tank, and
refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke
and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the pedal. Repeat the same work for each
wheel.
5. Bleed air. Refer to BR-11, "
Bleeding Brake System" .
Bleeding Brake System NFS000OX
CAUTION:
While bleeding, pay attention to master cylinder fluid level.
Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
1. Connect a vinyl tube to rear right brake caliper bleed valve.
2. Fully depress brake pedal 4 or 5 times.
3. With brake pedal depressed, loosen bleed valve to bleed air in brake line, and then tighten it immediately.
4. Repeat steps 2 and 3 until all of the air is out of the brake line.
5. Tighten the bleed valve to the specified torque. Refer to front disc brake: BR-23, "
Components" , rear disc
brake: BR-29, "
Components" .
6. From step 1 to 5, with master cylinder reservoir tank filled at least half way, bleed air from brake hydraulic
line bleed valves in the following order:

CAUTION:
All brake hoses and tubes must be free from excessive bending, twisting and pulling.
Make sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.
Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged
part is detected.
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.
Cover the open end of brake tubes and hoses when disconnecting to prevent entrance of dirt.
Refill with new brake fluid “DOT 3”.
Never reuse drained brake fluid.

Inspection after InstallationNFS000P1
CAUTION:
Brake tubes and hoses are important safety parts. Always disassemble the parts and retighten their fit-
tings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part is
detected.
1. Check brake lines (tubes and hoses) and connections for fluid leakage, damage, twists, deformation, con-
tacts with other parts, and loose connections. Replace any damage parts.
2. While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running for approximately
5 seconds, then check each part for fluid leakage.

ASSEMBLY
CAUTION:
Never use mineral oils such as kerosene, gasoline during the cleaning and assembly process.
Do not drop parts. If a part is dropped, do not use it.
