BRAKE TUBE AND HOSE
Revision: 2006 November2007 350Z
BRAKE TUBE AND HOSEPFP:46300
Hydraulic CircuitNFS0000B
CAUTION:

Make sure it does not twist or break when being attached.

Make sure there is no interference with other parts when turning steering both clockwise and
counterclockwise.

The brake tube is an important safety part. If a brake fluid leak is detected, always disassemble the
parts. Replace applicable part with a new one, if necessary.

Do not let brake fluid come in contact with painted surfaces on the body. This might damage the
paint, so if it does come in contact, immediately wipe area and wash off with water.

Do not bend or twist brake hose sharply, or strongly pull it.

When removing components, cover connections so that no dirt, dust, or other foreign matter gets
in.

Refill with new brake fluid “ DOT 3 ”.

Do not reuse drained brake fluid.
Removal and Installation of the Front Brake Tube and Brake Hose (Other than
Brembo Calipers)
NFS0000C
REMOVAL
1. Drain brake fluid. Refer to BR-10, "Drain and Refill" .
2. Using a flare nut wrench, remove brake tube from brake hose.
3. Remove union bolt and remove the brake hose from the caliper assembly.
4. Remove the lock plate and nut, and remove the brake hose from the vehicle.
INSTALLATION
1. Attach the brake hose to the vehicle and tighten the nut to the
specified torque.
NOTE:
When removed bracket attaching the bolt is tightened with provi-
sions torque.
2. Install brake hose by aligning with the protrusion on caliper
assembly, and tighten union bolts to the specified torque.

2. Attach pad.
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.
3. Insert the upper pad pin from the inner cylinder side, then insert
firmly to the outer cylinder side through the hole in the top of the
pad.
4. As shown in the figure, place the top of the cross spring over the
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.
Removal and Installation of Brake Caliper Assembly (Other than Brembo Cali-
pers)
NFS000AV
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Fasten disc rotor using wheel nut.
3. Drain brake fluid gradually (from bleed valve while depressing brake pedal). Refer to BR-10, "
Drain and
Refill" .
4. Remove union bolt, and then remove brake hose from caliper
assembly.
5. Remove torque member mounting bolts (from torque member),
and remove caliper assembly (from vehicle with a power tool).
CAUTION:
Do not drop brake pad.
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 caliper assembly to vehicle, and tighten torque member mounting bolts to the specified torque.
Refer to BR-27, "
Components" .
CAUTION:
Before installing torque member to vehicle, wipe oil and grease on washer seats on steering
knuckle and mounting surface of torque member.

5. Install the torque member to the steering knuckle and tighten the
mounting bolts to the specified torque. Refer to BR-27, "
Compo-
nents" .
CAUTION:
Before installing torque member to vehicle, wipe off oil and
grease on the washer seats on steering knuckle and the
mounting surface of the torque member.
6. Install pad retainers to torque member.
7. Press in piston until pads can be installed, and then install cylin-
der body to torque member.
8. Install cylinder body, and tighten sliding pin bolt to the specified
torque. Refer to BR-27, "
Components" .
9. Position a projection of brake hose metal fitting by aligning with protrusions on cylinder body and tighten
union bolt to specified torque. Refer to BR-12, "
Hydraulic Circuit" .
CAUTION:

Assemble brake hose securely to cylinder body.

Do not reuse copper washer for union bolts.
10. After installing caliper assembly, refill with new brake fluid and bleed air. Refer to BR-11, "
Bleeding Brake
System" .
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cracks, and serious damage. If a malfunction is detected,
replace applicable part.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
NOTE:
Make sure that wheel bearing axial end play is with in the speci-
fication before measuring runout. Refer to FA X - 4 , "
On-Vehicle
Inspection" .
3. If runout is outside limit, find the minimum runout point by shift-
ing the mounting positions of 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 disc rotor. If thickness is out-
side standard, replace disc rotor.
