BRAKE TUBE AND HOSE
Revision: 2006 January2006 M35/M45
3. Remove union bolts, and then remove brake hose from brake
caliper assembly.
4. Remove lock plate and then remove brake hose from vehicle.
INSTALLATION
1. Assemble the union bolt and copper washer to the brake hose.
CAUTION:
Do not reuse copper washer.
2. Attach L-shape metal fitting of the brake hose to brake caliper assembly positioning hole, and then tighten
union bolt to the specified torque. Refer to BR-12, "
Hydraulic Circuit" .
3. Connect brake hose to brake tube, partially tighten flare nut by hand as much as possible, then secure it
to the bracket with lock plate.
4. Using a flare nut torque wrench, tighten flare nut to the specified torque. Refer to BR-12, "
Hydraulic Cir-
cuit" .
5. Refill brake fluid and bleed air. Refer to BR-11, "
Bleeding Brake System" .
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" .

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 BOOSTER
Revision: 2006 January2006 M35/M45
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.
