5. Using a flat-bladed screwdriver, remove piston seals from cylin- der body.
CAUTION:
Be careful not to damage cylinder inner wall.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
 Use new brake fluid to clean. Do not use mine ral oils such as gasoline or kerosene.
 Check inside surface of cylinder for score, rust wear , damage or foreign materials. If any of the
above conditions are obser ved, replace cylinder body.
 Minor damage from rust or foreign materials m ay be eliminated by polishing surface with a fine
emery paper. Replace cylinder body if necessary.
Torque Member
Check for wear, cracks, and damage. If damage or def ormation is present, replace the torque member.
Piston
CAUTION:
 Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials are
stuck to sliding surface.
 Check piston for score, rust, wear , damage or presence of foreign materials. Replace if any of the
above condition are observed.
Sliding Pin Bolts and Sliding Pin Boots
Check sliding pin bolts and sliding pin boots, for wear, damage and cracks. If damage or deformation is
present, replace the applicable part.
ASSEMBLY
1. Apply polyglycol ether based lubricant to the piston seal, and install them to the cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply rubber grease to piston boots. Cover the piston end with piston boot, and install cylinder side lip on piston boots properly
into groove on cylinder body.
CAUTION:
Do not reuse piston boot.

3. Apply brake fluid to piston, and press piston into cylinder bodyby hand to assemble piston side lip on piston boot properly into
groove on piston.
CAUTION:
Press piston evenly and change the pressing point to pre-
vent the inner wall of cylinder from being rubbed.
4. Fix piston boot with retaining ring. CAUTION:
 Make sure boot is firmly in cylinder body groove.
 Do not reuse retaining ring.
5. Install sliding pin bolts and sliding pin boots to torque member.
6. Apply PBC (Poly Butyl Cuprysil) grease or silicone- based grease to the backside of brake pad and to both
sides of shim, and attach inner shim and shim cover to inner pad, and the outer shim to outer pad.
7. Assembling shims and shim cover to pad. CAUTION:
When attaching pad retainer, inst all it firmly so that it does
not float up higher than torque member, as shown in the fig-
ure.
8. Install brake pad retainer and pad to torque member.
9. Install cylinder body. Tighten sliding pin bolts to the specified torque. Refer to BR-24, "
Component".
10. After installing caliper assembly, refill with new brake fluid and bleed air. Refer to BR-8, "
Bleeding Brake System".
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cra cks, and serious damage. If a malfunction is detected,
replace applicable part.
Runout Inspection
1. Using wheel nuts, fix the disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that wheel bearing axle end
play is within the specification. Refer to RAX-6, "
On-Vehicle
Inspection".
3. If runout is outside the limit, find minimum runout point by shift- ing 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 Br ake Lathe (Tool No, 38-PFM90.5) or equivalent.]
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
Brake Burnishing ProcedureINFOID:0000000001327638
Burnish the brake pad or lining contact surfaces of rotor according to following procedure after refinishing or
replacing drums or rotors, after replacing pads or li nings, or if a soft pedal occurs at very low mileage.
CAUTION:
 Be careful of vehicle speed because brake does no t operate easily until pad and disc rotor are
securely fitted.
 Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicl e within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted. Standard thickness : 16.0 mm (0.630 in)
Wear limit : 14.0 mm (0.551 in)
Maximum uneven wear
(measured at 8 positions)
: 0.015 mm (0.0006 in) or

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612923
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Brake SystemINFOID:0000000001327654
 Recommended fluid is brake fluid “DOT 3”. Refer to MA-9.
 Do not reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off and flush area with water immediately.
 Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause improper operation.
 Using a flare nut crowfoot and torque wrench, securely tighten brake tube flare nuts.
 Brake system is an important safe ty part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction is
detected, replace part with a new one.
 Before working, turn ignition switch OFF and disconnect electrical
connectors of ABS actuator and elec tric unit (control unit) or bat-
tery negative terminal.
 When installing brake piping, be sure to check torque.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precaution for Brake ControlINFOID:0000000001327655
 During VDC/TCS/ABS operation, brake pedal lightly vi brates and a mechanical noise may be heard. This is
normal.
 Just after starting vehicle after turning ignition switch ON, brake pedal may vibrate or motor operating noise
may be heard from engine room. This is a normal status of operation check.
 Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
 When an error is indicated by ABS or another warning lamp, collect all necessary information from customer
(what symptoms are present under what conditions) and check for simple causes before starting diagnostic
servicing. Besides electrical system inspection, c heck booster operation, brake fluid level, and fluid leaks.
 If tire size and type are used in an improper combinat ion, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
 If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, VDC/TCS/ABS
function may have a malfunction or error.
 If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
