BRAKE MASTER CYLINDER
1. Apply brake fluid to the inner wall of cylinder body, primary pis-
ton assembly and secondary piston assembly.
2. Insert secondary piston and primary piston assembly into cylin-
der body in this order.
CAUTION:
Pay attention to the orientation of piston cup, and insert
straight to prevent cup from being caught by the inner
wall of cylinder.
Always replace inner kit as a set.
3. Set the slit of secondary piston towards the piston stopper
mounting hole of cylinder body while pushing in the primary pis-
ton. Then install the piston stopper through the slit of secondary
piston.
4. Insert plate and guide assembly into cylinder body.
CAUTION:
Be careful not to damage rod of primary piston.
Pay attention to the orientation of guide assembly.
Do not drop O-ring.
Be careful the guide and/or plate are not inserted at an
angle to cylinder inner wall.
5. Be careful not to damage rod of primary piston with the cloth.
Then insert snap ring to cylinder body while pushing primary pis-
ton.
CAUTION:
Make sure that snap ring is securely engaged in cylinder
body inner diameter groove.
6. Apply brake fluid to a grommet, and press it into reservoir tank to install.

Disassembly and Assembly of Brake Caliper AssemblyINFOID:0000000001717023
NOTE:
Do not remove torque member, brake pads, shims and pad retainers, when disassembling or assembling cyl-
inder body.
DISASSEMBLY
1. Remove caliper assembly from vehicle. Refer to BR-25,
"Removal and Installation of Brake Caliper Assembly" .
2. Remove sliding pin bolts from cylinder body, and remove pads,
shims and pad retainers from torque member, if necessary.
CAUTION:
When removing pad retainer from torque member, lift the
pad retainer in the direction shown by arrow, so as not to
deform it.
3. Remove sliding pins and sliding pin boots from torque member.
4. Place a wooden block as shown, and blow air from union bolt
mounting hole to remove piston and piston boot.
CAUTION:
Do not get fingers caught in the piston.
5. Remove piston seal with a flat-bladed screwdriver.
CAUTION:
Be careful not to damage the inner wall of cylinder.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of cylinder for corrosion, wear, and damage. Replace cylinder body as necessary.
CAUTION:
Clean cylinder body using new brake fluid. Never use mineral oils such as gasoline or kerosene.
Torque Member
Check for wear, cracks, and damage. Replace torque member as necessary..
Piston
Check piston surface for corrosion, wear, and damage. Replace piston as necessary.
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.

Check sliding pins, sliding pin bolts and sliding pin boots for wear, damage, and cracks. Replace applicable
part as necessary.
ASSEMBLY
CAUTION:
When assembling, use only specified rubber lubricant.
1. Apply polyglycol ether based lubricant to new piston seal and
install them to cylinder body.
2. Apply rubber grease to piston boot and apply brake fluid to pis-
ton. Cover the piston end with piston boot, and install cylinder-
side lip on piston boot properly into groove on cylinder body.
3. Press piston into cylinder body by hand to assemble piston-side
lip on piston boot properly into a groove on piston.
CAUTION:
Press piston evenly and change pressing point to prevent
inner wall of cylinder from being rubbed.
4. Install sliding pins and sliding pin boots to the torque member.
5. If pads, shims and pad retainers were removed, install them to torque member. Refer to BR-24, "
Removal
and Installation of Brake Pad" .
6. Install cylinder body to torque member.
7. Install sliding pin bolts.
8. Install caliper assembly to vehicle. Refer to BR-25, "
Removal and Installation of Brake Caliper Assembly"
.
9. Tighten sliding pin bolts to specified torque. Refer to BR-24, "
Component" .
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cracks, and serious damage. Replace applicable part as neces-
sary.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheels hub 2 or more positions.

DISASSEMBLY
1. Remove the sliding pin bolt, and then remove the pad, shim, shim cover, and pad retainer from the torque
member and cylinder.
2. Remove sliding pin boot from torque member.
3. Remove the retaining ring from the cylinder body using a screw-
driver or suitable tool, as shown.
4. Place a wooden block as shown, and blow air from connecting
bolt mounting hole to remove pistons and piston boots.
WARNING:
Do not place your finger in front of piston.
5. Remove piston seals from cylinder body using a screwdriver or
suitable tool, as shown.
CAUTION:
Be careful not to damage cylinder inner wall.
CALIPER INSPECTION
Cylinder Body
CAUTION:
Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.
Check inner wall of cylinder for corrosion, wear, and damage. If any non-standard condition is
detected, replace cylinder body.
Minor flaws caused by corrosion or a foreign material can be removed by polishing the surface with
a fine sandpaper. Replace the cylinder body, if necessary.
Torque Member
Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.
Piston

REAR DISC BRAKE
Since the piston surface is plated, do not repair using sandpaper.
Check piston surface for corrosion, wear, and damage. If any non-standard condition is detected, replace
applicable part.
Sliding Pin Bolts and Sliding Pin Boots
Check that there is no wear, damage, or cracks in the sliding pin bolts and sliding pin boots, and if there are,
replace them.
ASSEMBLY
CAUTION:
Do not use Nissan Rubber Grease (KRE00 00010 or KRE00 00010 01) when assembling.
1. Apply a rubber grease to the piston seal and attach to cylinder
body.
CAUTION:
Do not reuse the piston seals.
2. Apply brake fluid or rubber grease to the piston boot, place it on
the piston, and firmly insert the piston boot cylinder-side lip into
the cylinder body groove.
CAUTION:
Do not reuse the piston boot.
3. Apply a brake fluid to the piston, insert into the cylinder body by
hand and firmly attach the piston boot piston-side lip into the pis-
ton boot.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
4. Fix piston boot with retaining ring.
CAUTION:
Make sure the boot is firmly in the cylinder body groove.
Do not reuse the retaining ring.
