ComponentsNFS00010
OTHER THAN BREMBO CALIPERS
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, never depress the brake pedal because the piston will pop out.
It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of the 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 shims and shim covers as a set when replacing brake pads.
Keep disc rotor clean of brake fluid.

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, never depress the brake pedal because the piston will pop out.
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.
Always replace shim covers as a set when replacing brake pads.

Removal and Installation of Brake Pad (Other than Brembo Calipers)NFS00011
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove sliding pin bold (one on top).
3. Hang cylinder body with a wire, and remove pads, pad retainers, shims and shim cover from torque mem-
ber.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the rear of the pad and to both sides
of the shim, and attach the inner shim and shim cover to the inner pad, and the outer shim to the outer
pad.
2. Attach the pad retainer and pad to the torque member.
3. Push the piston in so that the pad is firmly attached and attach the cylinder body to the torque member.
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.
4. Attach the sliding pin bolt (one on top) and tighten to the specified torque.
5. Check brake for drag.
6. Install tires to vehicle.
Removal and Installation of Brake Pad (With Brembo Calipers)NFS00016
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.

Removal and Installation of Brake Caliper Assembly (With Brembo Calipers)NFS00017
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Drain brake fluid. Refer to BR-10, "
Drain and Refill" .
3. Remove the brake pad. Refer to BR-42, "
Removal and Installa-
tion of Brake Pad (With Brembo Calipers)" .
4. Remove the brake tube flare nut using a flare wrench.
5. Remove the brake hose bolt, move the brake hose, and remove
the caliper assembly from the vehicle.
6. Remove disc rotor.
CAUTION:
Put matching marks on wheel hub assembly and disc rotor,
if it is necessary to remove disc rotor.
INSTALLATION
CAUTION:
Refill with new brake fluid “DOT 3”.
Do not reuse drained brake fluid.
1. Install disc rotor.
CAUTION:
Put alignment marks on disc rotor and wheel hub at the time of removal when reusing disc rotor.
2. Install the brake tube to the caliper assembly and partially tighten the flare nut.
3. Install the caliper assembly to the vehicle and tighten the bolt to
the specified torque.
4. Tighten the flare nut to the specified torque.
5. Install brake pad and shim. Refer to BR-42, "
Removal and
Installation of Brake Pad (With Brembo Calipers)" .
6. Refill new brake fluid and bleed air. Refer to BR-11, "
Bleeding
Brake System" .

7. Install the pad retainers and pads to the torque member.
CAUTION:
When attaching the pad retainer, attach it firmly so that it
does not float up higher than the torque member, as shown
in the figure.
8. After assembling shims and shim cover to pad, install it to the
torque member.
9. Install cylinder body. Tighten sliding pin bolts to the specified
torque. Refer to BR-40, "
Components" .
DISC ROTOR INSPECTION
Visual Inspection
Check surface of the disc rotor for uneven wear, cracks, and serious damage. If any non-standard condition is
detected, replace applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to the wheel hub. (2 or more positions)
2. Inspect runout using a dial gauge.
NOTE:
Make sure that wheel bearing axial end play is with in the specification before measuring runout. Refer to
RAX-6, "
On-Vehicle Inspection" .
3. If runout is outside the limit, find the minimum runout point by shifting mounting positions of the disc rotor
and wheel hub by one hole.
4. If runout is still outside the limit after performing the above operation, replace or lathe the disc rotor.
[When lathing, use the Pro–Cut PFM On–Car Brake Lathe (Tool No. 38–PFM90.5) or equivalent.]
Thickness Inspection
Using a micrometer, check thickness of the disc rotor. If thickness is
outside the standard, replace disc rotor.
