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.
InspectionNFS0000O
VISUAL INSPECTION
Check for improper assembly, damage and deteriorate.

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
Burnishing Procedure" .

NOTE:
Refer to BR-30, "
HOW TO APPLY GREASE TO THE BRAKE PAD" for how to apply grease to brake pads.
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.

Do not damage piston boot.

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
Burnishing Procedure" .
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.

CAUTION:

Attach the pad with wear sensor to the outer side.

The side of the shim with the larger cutouts should be on
the entry side of the disc rotor spin.

top pad pin, press in the cross spring, push the lower pad pin
from the inner cylinder side to the outer cylinder side, and
secure the cross spring.
5. Insert the clip in the small hole at the end of the pad pin.
CAUTION:
If the clip is not fully attached, the pad pin or the pad could
fall out while the vehicle is in motion.
6. Install tires to vehicle.
