CALIPER INSPECTION
Cylinder Body

CAUTION:

●

Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

●

Check inside surface of cylinder for score, rust, wear, damage or presence of foreign materials. If
any of the above conditions are observed, replace cylinder body.

●

Minor damage from rust or foreign materials may be eliminated by polishing surface with a fine
emery paper. Replace cylinder body if necessary.

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 conditions are observed.

Check piston surface for corrosion, wear, and damage. If any non-standard condition is detected, replace
applicable part.

Sliding Pin, and Sliding Pin Boot

Check sliding pin and sliding pin boot for wear, damage, and cracks. If damage or deformation is present,
replace the applicable part.

DISC ROTOR INSPECTION
Visual Inspection

Check surface of the disc rotor for uneven wear, cracks, and serious damage. If any of them is detected,
replace applicable part.

Runout Inspection

Using wheel nuts, fix disc rotor to the wheel hub. (2 or more positions)

Check runout using a dial indicator.
[measured at 10 mm (0.39 in) inside the disc edge]

NOTE:
Make sure that wheel bearing axial end play is with in the speci-
fications before measuring runout. Refer to

FAX-5, "FRONT

WHEEL HUB AND KNUCKLE"

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.

If runout still out of specification, turn rotor with on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and
705” or equivalent).

Thickness Inspection

Using a micrometer, check thickness of the disc rotor. If thickness is
outside the standard, replace disc rotor.

BRAKE BURNISHING PROCEDURE

Burnish the brake contact surface according to the following procedure after refinishing or replacing rotors,
after replacing pads, or if a soft pedal occurs at very low mileage.

CAUTION:

Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1.

Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).

Use medium brake pedal /foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH).
Adjust brake pedal /foot pressure such that vehicle stopping time equals 3 to 5 seconds.

To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.

Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.

WARNING:

●

Clean dust on caliper and brake pad with a vacuum dust collector to minimize of air borne parti-
cles 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, suspend 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.

●

Burnish the brake contact surface after refinishing or replacing rotors, after replacing pads, or it a
soft pedal occurs at very low mileage. Refer to

BR-38, "BRAKE BURNISHING PROCEDURE"

PRECAUTIONS

PFP:00001

Precautions for Brake System

AFS001ZN

●

Recommended fluid is brake fluid “DOT 3”.

●

Do not reuse drained brake fluid.

●

Be careful not to splash brake fluid on painted areas.

●

To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.

●

Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

●

Use flare nut wrench when removing and installing brake tube.

●

Always torque brake lines when installing.

●

Before working, turn ignition switch OFF and disconnect electri-
cal connectors of ABS actuator and electric control unit or bat-
tery terminals.

●

Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to

BR-32, "BRAKE BURNISHING PROCEDURE"

WARNING:

Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.

Precautions for Brake Control

AFS0018B

●

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

●

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. 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 cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and fluid leaks.

●

If tire size and type are used in an improper combination, 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, 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.
