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. Brake booster will not operate normally if
hose is installed in the wrong direction.
●
Insert vacuum hose for at least 24 mm (0.94 in).
●
Never use lubricating oil during assembly.

Inspection
NFS0005N
VISUAL INSPECTION
Check for improper assembly, damage and aging.
CHECK VALVE INSPECTION
Airtightness Inspection
Use a handy vacuum pump to check.
When connected to booster side (1):
Vacuum decrease should be 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 engine side (2):
No vacuum will be applied

PAD WEAR INSPECTION
●
Check pad thickness from an inspection hole on cylinder body.
Use a scale for inspection if necessary.
Components
NFS000JV
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.

Refer to
and the followings for the symbols in the figure.
1: Apply rubber grease.
2: Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease.
3: Apply polyglycol ether based lubricant.
: Apply brake fluid.

FRONT DISC BRAKE
●
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 as not to stretch brake hose.
●
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 rotor clean, from 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
.
Removal and Installation of Brake Pad
NFS000JW
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, shim
covers 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 rotor clean, from 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.
Push the piston in so that the pad is firmly installed, and install
cylinder body to torque member.
CAUTION:
When replacing pads with new ones, press in piston until pads can be installed. In this case, care-
fully monitor brake fluid level in reservoir tank because brake fluid will return to master cylinder
reservoir tank.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press piston.
4.
Install lower sliding pin bolt, and tighten it to the specified torque. Refer to
5.
Secure disc rotor with wheel nuts. Depress brake pedal a few times until it gets a responsive touch.
