2.

Inspect runout using a dial gauge. [Measured at 10 mm (0.39 in)
inside the disc edge.]

NOTE:
Make sure that wheel bearing axial end play is within the specifi-
cations before measuring runout. Refer to 

FAX-5, "On-Vehicle

Inspection and Service"

.

3.

If runout is outside the limit, find the minimum runout point by
shifting mounting positions of disc rotor and wheel hub by one
hole.

4.

If runout still out of specification, turn rotor with on-car brake lathe.

Thickness Inspection

Using a micrometer, check thickness of disc rotor. If thickness is
either at or below the wear limit, or exceeds maximum uneven wear,
replace disc rotor.

Runout limit (on vehicle)

: 0.05 mm (0.0020 in)

CAUTION:

• While removing cylinder body, never depress brake pedal because piston will pop out.
• It is not necessary to remove bolts on torque member and brake hose except for disassembly or

replacement of cylinder body. In this case, hang cylinder body with a wire so as not to stretch brake
hose.

• Do not damage piston boot.
• Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or it a soft

pedal occurs at very low mileage. Refer to 

BR-14, "Brake Burnishing"

.

Disassembly and Assembly of Brake Caliper

INFOID:0000000001297488

DISASSEMBLY

1.

Remove pads from cylinder body.

2.

Remove sliding sleeve and boot from cylinder body.

3.

Place a wooden block as shown, and blow air from union bolt
hole to remove piston and piston boot.

CAUTION:

Do not get your fingers caught in piston.

4.

Remove piston seal from cylinder body, using a suitable tool.

CAUTION:

Be careful not to damage cylinder inner wall.

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 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.

Torque Member

Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.

Piston

CAUTION:

• Piston sliding surface is plated, do not polish with emery paper even if rust or 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. 

Sliding Pin Bolts and Sliding Pin Boots

Make sure there is no wear, damage, or cracks in sliding sleeve and sliding sleeve boots, and if there are,
replace them.

REAR DISC BRAKE

ASSEMBLY

CAUTION:

Do not use NISSAN Rubber Grease (KRE00 00010, KRE00 00010 01) when assembling.

1.

Apply clean brake fluid to new piston seal and insert into groove
on cylinder body.

CAUTION:

Do not reuse piston seal.

2.

Apply brake fluid to piston and to piston boot, then install piston
boot into piston groove. 

CAUTION:

Do not reuse piston boot.

3.

Insert into cylinder body by hand and insert piston boot piston-side lip into piston groove.

CAUTION:

Press piston evenly and vary the pressing point to prevent cylinder inner wall from being rubbed.

4.

Install sliding boots and sleeves to cylinder body.

DISC ROTOR INSPECTION

Visual Inspection

Check surface of disc rotor for uneven wear, cracks, and serious damage. If any non-standard condition is
detected, replace applicable part.

Runout Inspection

1.

Install disc rotor to wheel hub in 2 or more positions, using wheel nuts.

2.

Inspect runout using a dial gauge. [Measured at 10 mm (0.39 in)
inside disk edge.]

NOTE:
Make sure that wheel bearing axial end play is within the specifi-
cation before measuring runout. Refer to 

RAX-8, "Removal and

Installation"

.

3.

If runout is outside the limit, find the minimum runout point by
shifting mounting positions of disc rotor and wheel hub by one
hole.

4.

If runout still out of specification, turn rotor with on-car brake lathe.
