DISASSEMBLY
CAUTION:
Master cylinder cannot be disassembled.
Remove reservoir tank only when absolutely necessary.
When securing master cylinder assembly in a vise, be sure not to over-tighten.
When securing in a vise use copper plates or cloth to protect the flange.
1. Using a pin punch [commercial service tool: diameter approxi-
mately 4 mm (0.16 in)], remove mounting pin on reservoir tank.
2. Remove reservoir tank and grommet from cylinder body.
1. Reservoir cap 2. Oil strainer 3. Reservoir tank
4. Grommet 5. Pin 6. Master cylinder assembly
7. O-ring 8. Brake fluid level switch connector
: PBC (Poly Butyl Cuprysil) grease
or silicone-based grease: Brake fluid

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.

BRAKE BOOSTERPFP:47200
On-Board Inspection and ServiceNFS000P6
OPERATION CHECK
With engine stopped, change vacuum to atmospheric pressure by
depressing brake pedal several times. Then with brake pedal fully
depressed, start engine and when vacuum pressure reaches the
standard, make sure that clearance between brake pedal and floor
panel decreases.
AIR TIGHT CHECK
Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change vacuum to atmospheric pressure. Make sure that dis-
tance at intervals of 5 seconds between brake pedal and floor
panel gradually increases.
Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change after
holding pedal down for 30 seconds.

Removal and InstallationNFS000P7
COMPONENTS
CAUTION:
Be careful not to deform or bend brake tube while removing and installing brake booster.
Replace clevis pin if it is damaged.
Be careful not to damage brake booster stud bolt threads. If brake booster is tilted during installa-
tion, the dash panel may damage the threads.
REMOVAL
1. Remove cowl top. Refer to EI-18, "Removal and Installation" .
2. Remove brake master cylinder. Refer to BR-15, "
Removal and
Installation" .
3. Disconnect front left brake tube from ABS actuator and electric
unit (control unit). Refer to BR-12, "
Hydraulic Circuit" .
4. Remove vacuum hose from brake booster. Refer to BR-21,
"Components" .
5. Remove snap pin and clevis pin from inside vehicle.
6. Remove nuts on brake booster and brake pedal assembly.
7. Remove brake booster from dash panel in engine room side.
INSTALLATION
1. Loosen lock nut to adjust input rod length so that length B (in the
figure) satisfies the specified value.
2. After adjusting "B", temporarily tighten lock nut to install booster
assembly to vehicle. At this time, make sure that a gasket
between booster assembly and dash panel is installed.
CAUTION:
Always install gasket between brake booster and dash
panel.
3. Connect brake pedal with clevis of input rod.

Removal and InstallationNFS000P9
CAUTION:
Because vacuum hose contains a check valve, it must be
installed in the correct position. Refer to the stamp to con-
firm correct installation. Brake booster will not operate nor-
mally if the hose is installed in the wrong direction.
Insert vacuum hose at least 24 mm (0.94 in).
Do not use lubricating oil during assembly.
InspectionNFS000PA
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.
SBR225B
When connected to the booster side (1):
Vacuum should decrease within 1.3 kPa (10
mmHg, 0.39 inHg) for 15 seconds under a vacuum
of
66.7 kPa (500 mmHg, 19.69 inHg).
When connected to the engine side (2):
Vacuum should not exist.

WAR NING :
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air borne
particles or other materials.
CAUTION:
While removing cylinder body, do not depress brake pedal because piston will pop out. Standard thickness : 11.0 mm (0.433 in)
