Pay attention to the orientation of the piston cup, and insert straight to prevent the cup from
being caught by cylinder inner wall.
3. Perform a visually inspection of the secondary piston slit through
the tank boss hole on the secondary-side of the cylinder body,
and install the piston stopper.
4. Insert the plate and guide into the cylinder body.
CAUTION:

Make sure not to damage the primary piston rod.

Pay attention to the direction of the guide.

Do not drop the O-ring.

Make sure the guide and/or plate are not inserted at an
angle.
5. Cover the primary piston rod with cloth to prevent it getting dam-
aged, and attach the snap ring with the primary piston pushed
in.
CAUTION:

Make sure the area around the snap ring is snug in the
cylinder body bore groove.

Do not reuse the snap ring.
6. Place the side of the cylinder body with chamfering around the
pin insertion hole up, and secure the cylinder body flange sec-
tion with a vise.
CAUTION:
When securing in a vise, use copper plates or cloth to pro-
tect the flange.
7. Apply brake fluid to the grommet and attach the reservoir tank to
the master cylinder.
CAUTION:
Do not reuse the grommet.

NOTE:
Attach the reservoir tank in the orientation shown in the figure.
8. Tilt the reservoir tank so that the mounting pin can be inserted
as shown in the figure, and insert the mounting pin. When the
mounting pin has passed the master cylinder pinhole, return the
reservoir tank to a level position. Attach the mounting pin to the
opposite mounting pin hole of the reservoir tank so that it is the
same as the insertion side.
CAUTION:

Be sure to insert pin from the chamfered pinhole of cylin-
der body.

Do not reuse reservoir tank and mounting pin.

On-Vehicle InspectionNFS0000L
OPERATING CHECK
With the engine stopped, change the vacuum to the atmospheric
pressure by depressing the brake pedal several times. Then with
brake pedal fully depressed, start the engine and when the vacuum
pressure reaches the standard, check that the clearance between
the brake pedal and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIRTIGHT CHECK

Run the engine at idle for approximately 1 minute, and stop it
after applying vacuum to the booster. Depress the brake pedal
normally to change the vacuum to the atmospheric pressure.
Check that distance between the 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.
CAUTION:
Depressing pedal interval is approximately 5 seconds.

CAUTION:

Be careful not to deform or bend brake piping while removing and installing the brake booster.

Replace clevis pin if it is damaged.

Be careful not to damage brake booster stud bolt threads. If brake booster is tilted or inclined dur-
ing installation, the dash panel may damage the threads.

Attach the check valve in the correct orientation.
1. Remove vacuum hose from the brake booster. Refer to BR-25, "
VACUUM LINES" .
2. Remove the brake master cylinder. Refer to BR-24, "
Removal and Installation" .
3. Remove the brake piping between brake master cylinder and ABS actuator and electric unit (control unit).
Refer to BR-12, "
Hydraulic Circuit" .
CAUTION:
For M/T vehicles with remove the brake piping after removing the clutch reservoir tank bolt.
4. Remove the brake pedal attachment snap pin and clevis pin from inside the vehicle.
5. Remove the nuts on the brake booster and brake pedal assembly.
6. Remove brake booster assembly from the engine compartment side.
INSPECTION AFTER REMOVAL
Output Rod Length Inspection
1. Using a handy vacuum pump, apply a vacuum of −66.7 kPa (−
500 mmHg,−19.69 inHg) to the brake booster.
2. Check output rod length.
INSTALLATION
1. Loosen the lock nut to adjust the input rod length so that the
length “B” (in the figure on the right) satisfies the specified value.
2. After adjusting “B”, temporarily tighten the lock nut to install the
booster assembly to the vehicle. At this time, make sure to
install a gasket between the booster assembly and the vehicle.
3. Connect the brake pedal with the clevis of the input rod.
4. Install the pedal bracket mounting nuts and tighten them to the
specified torque.
5. Install the brake piping between brake master cylinder and ABS
actuator and electric unit (control unit). Refer to BR-12, "
Hydraulic Circuit" .
6. Install the master cylinder to the booster assembly. Refer to BR-24, "
Removal and Installation" .
7. Adjust the height and play of the brake pedal. Refer to BR-7, "
ADJUSTMENT" .
8. Tighten the lock nut of the input rod to the specified torque. Refer to BR-23, "
Components" .
9. Refill new brake fluid and bleed air. Refer to BR-11, "
Bleeding Brake System" . Standard dimension when vacuum −66.7 kPa

CAUTION:

Because vacuum hose contains a check valve, it must be
installed in the correct orientation. Refer to the stamp or
label to confirm correct installation. The brake booster will
not operate normally if the hose is installed in the wrong
direction.

Insert the vacuum hose for at least 24 mm (0.94 in).

Do not use lubricating oil during assembly.

WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne
particles or other materials.
CAUTION:

While removing cylinder body, do not depress brake pedal because piston will pop out.

It is not necessary to remove torque member mounting bolts on torque member and brake hose
except for disassembly or replacement of caliper assembly. In this case, hang cylinder body with a
wire so that brake hose is not under tension.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shim and shim covers as a set when replacing brake pads.

Keep disc rotor clean of brake fluid.

Burnish the brake pads and disc rotor mutually contacting surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low mileage. Refer to BR-38, "
Brake

WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne
particles or other materials.
CAUTION:

While the brake pad and cylinder body are separated, the piston may suddenly jump out, so do not
depress the brake pedal.

Apart from caliper assembly, disassembly or replacement, there is no need to remove caliper bolts
or brake hose or tube.

Removal and Installation of Brake Pad (Other than Brembo Calipers)NFS000AU
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, shims and
pad retainers from torque member.
CAUTION:

When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow (shown in the
figure) so as not to deform it.

Do not damage piston boot.

Keep disc rotor clean of brake fluid.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based
grease between pad retainer and pad.
2. Install pad retainers and pad assemblies to torque member.
CAUTION:
Inner pad and outer pad have pad-return mechanism on
upper side of pad retainer. When installing pad to torque
member, be sure to install pad return lever to pad wear sen-
sor securely.
3. Install cylinder body to torque member.
CAUTION:
When replacing pads with new ones, press in piston until
pads can be installed. In this case, carefully monitor brake fluid level in reservoir tank because
brake fluid will return to master cylinder reservoir tank.
4. Install lower sliding pin bolt, and tighten it to the specified torque. Refer to BR-27, "
Components" .
5. Secure disc rotor with wheel nuts. Depress brake pedal a few times until it gets a responsive touch.
6. Check front disc brake for drag.
7. Install tires to vehicle.

Removal and Installation of Brake Pad (With Brembo Calipers)NFS0000W
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove the clip from the pad pin.
3. Remove the pad pin while holding down the cross spring, then
remove the cross spring from the caliper.
4. Using pliers, remove the pad from the caliper.
HOW TO APPLY GREASE TO THE BRAKE PAD
Pad Side
Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease
about 0.5 g (0.018 oz) per surface equally to back plate side of Inner
Pad and Outer Pad. (Refer to the figure.)
CAUTION:
Make sure no foreign matter attaches itself to the grease.
INSTALLATION
1. Insert the piston to the position where the pad is attached.
NOTE:
Using a disc brake piston tool (commercial service tool), etc., makes it easier to push in the piston.
CAUTION:
By pushing in the piston, the brake fluid returns to the master cylinder reservoir tank. Watch the
level of the surface of the reservoir tank.
