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.

LEAK INSPECTION
Check for leaking in a master cylinder installation surface, a reservoir tank installation surface, and brake
tube connections.
Removal and InstallationNFS000P3
CAUTION:
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.
Never scratch the piston of master cylinder when installing/removing because the piston is
exposed. Check if any dust is not on the piston, and wash with brake fluid if needed.
Hold cylinder body when handing master cylinder. Never hold the piston because the piston might
be detached if pulled strongly.
REMOVAL
1. Drain brake fluid. Refer to BR-10, "Drain and Refill" .
2. Disconnect brake fluid level switch harness connector.
3. Disconnect master cylinder brake tubes, using a flare nut wrench.
4. Remove master cylinder mounting nuts and remove master cylinder assembly from vehicle.
INSTALLATION
CAUTION:
Refill with new brake fluid “DOT 3”.
Never reuse drained brake fluid.
1. Installation is in the reverse order of removal.
CAUTION:
Apply silicone grease to brake booster (to “A” position in
the figure) when installing master cylinder to brake booster.
2. Tighten brake tube flare nut to the specified torque using a flare
nut torque wrench. Refer to BR-12, "
Hydraulic Circuit" .
3. Refill with new brake fluid and bleed air. Refer to BR-11, "
Bleed-
ing Brake System" .

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.
1. Apply brake fluid to the grommet and attach it to the cylinder body.
CAUTION:
Do not reuse grommet.
2. Install reservoir tank onto the cylinder body.
3. Secure master cylinder assembly into a vise with a chamfered
pin insert hole on cylinder body facing upward.
4. Tilt reservoir tank as shown in the figure and insert mounting pin.
Return reservoir tank to a upright position when mounting pin
passes through the pinhole in the cylinder body. Push the
mounting pin to the opposite pinhole of the reservoir tank so that
it is the same conditions as the insertion side.
CAUTION:
Be sure to fix the flange part with the brake tube installa-
tion side of cylinder body up.
Do not reuse mounting pin.

VISUAL INSPECTION
Check for correct assembly, damage and deterioration.
CHECK VALVE INSPECTION
Airtightness Inspection
Use a handy vacuum pump to check.
Replace vacuum hose assembly if vacuum hose and check
valve are malfunctioning.
