PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001716907
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Brake SystemINFOID:0000000001716908
Refill using recommended brake fluid. Refer to MA-19, "Fluids and Lubricants".
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted surfaces
of body immediately wipe it off with cloth and then wash it away with water.
To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
Use a flare nut wrench when removing a brake tube and use a
flare nut torque wrench when installing a brake tube.
When installing brake tubes and hoses, be sure to check torque.
Before working, turn ignition switch OFF and disconnect connec-
tors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
Burnish the new braking surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer toBR-26, "
Brake Burnishing" .

3. With brake pedal depressed, loosen bleed valve to let the air out, and then tighten it immediately.
4. Repeat steps 2, 3 until no more air comes out.
5. Tighten bleed valve to specified torque. Refer to BR-24, "
Component" (front disc brake), BR-27, "Compo-
nent" (rear drum brake).
6. Following the steps 1 to 5 above, with master cylinder reservoir tank filled at least half way, bleed air from
the rear right, front left, rear left, and front right brake, in that order.

BRAKE TUBE AND HOSE
Hydraulic CircuitINFOID:0000000001716982
NOTE:
LHD shown RHD similar.
CAUTION:
All tubes and hoses must be free from excessive bending, twisting and pulling.
Make sure there is no interference with other parts when turning steering both clockwise and coun-
terclockwise.
Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part
is detected.
Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe them with cloth and then wash it away with
water.
Do not bend or twist brake hose sharply, or strongly pull it.
When removing components, cover brake line connections so that dirt, dust, or other foreign mat-
ters do not get in.
Refill using recommended brake fluid. Refer to MA-19, "
Fluids and Lubricants".
Never reuse drained brake fluid.

DUAL PROPORTIONING VALVE
Removal and InstallationINFOID:0000000001726771
Removal
1. Disconnect brake lines from dual proportioning valve.
Mark brake lines for installation.
2. Remove dual proportioning valve bolt and dual proportioning valve.
3. Remove two bolts and bracket.
Installation
Installation is in the reverse order of removal.
When installing brake lines to the dual proportioning valve, tighten to specifications. Refer to BR-14,
"Hydraulic Circuit".
InspectionINFOID:0000000001726772
CAUTION:
Carefully monitor brake fluid level at master cylinder.
Use the recommended new brake fluid. Refer to MA-19, "
Fluids and Lubricants".
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on paint areas, wash it away with water immediately.
1. Connect commercially available brake fluid pressure gauge to
air bleeders of front and rear brakes on either LH and RH side.
2. Bleed air from the Tool.
3. Check fluid pressure by depressing brake pedal.
Unit: kPa (kg/cm2, psi)
If output pressure is out of specification, replace dual proportioning valve.

CAUTION:
Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed air.
While removing brake pad or cylinder body, do not depress brake pedal because piston will pop out.
It is not necessary to remove torque member mounting bolts 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.
Keep rotor free from brake fluid.
When replacing brake pad, replace shim with a new one.

2. Remove sliding pin bolt (lower side).
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, so as not to
deform it.
INSTALLATION
1. Apply M-77 grease or equivalent to the shims. Install shims to pads.
CAUTION:
Securely install shims according to mounting direction of pads.
2. Apply M7439 grease or equivalent to pad contact surface on pad retainers. Install pad retainers and pads
to the torque member.
CAUTION:
When installing pad retainer, attach it firmly so that it is
not lifted up from torque member, as shown.
3. Install cylinder body to torque member.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press to piston in.
CAUTION:
Check the brake fluid level in the reservoir tank for fluid level because brake fluid returns to mas-
ter cylinder reservoir tank when pressing piston in.
4. Install lower sliding pin bolt (lower side), and tighten it to the specified torque. Refer to BR-24, "
Compo-
nent" .
5. Check brake for drag.
6. Install tires to the vehicle.
