BRAKE MASTER CYLINDER
Revision: 2006 November2007 350Z
Inspection after Disassembly
Master cylinder

Check that there is no damage, friction, rusting, or pinholes on the cylinder inner wall, and replace if there
are any non-standard conditions.
Assembly
CAUTION:

Do not use mineral oils such as kerosene, gasoline during the cleaning and assembly process.

Make sure there is no foreign matter such as dirt or dust attached to the inner cylinder walls, the
piston, or the cap seal, and use care to avoid damaging parts with the assembly tools.

Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to cylinder inner wall body and contact surface
of the piston assembly.
2. Insert the secondary piston assembly and primary piston
assembly into cylinder body in this order.
CAUTION:

Do not reuse the primary and secondary piston assem-
blies.

Be sure to replace the assembly without disassembling
the new inner kit.

Pay attention to the orientation of the piston cup, and
insert straight to prevent the cup from being caught by
cylinder inner wall.
3. Perform a visual inspection of the secondary piston slit through
the tank boss hole on the secondary-side of the cylinder body,
and install the piston stopper.
4. Holding down the piston with the stopper cap, push the stopper
cap tabs so they are firmly into the cylinder grooves, then attach
the stopper cap.
CAUTION:
Do not reuse the stopper cap.
5. Apply brake fluid the grommet and attach to the cylinder body.
CAUTION:
Do not reuse the grommet.
6. Attach the attachment in the inner kit to the reservoir cap as
described in disassembly step 2.
7. Master cylinder assembly is fixed in the vise as described in
disassembly step 3.SBR089C

5. Push in the primary piston and remove the piston stopper from
the cylinder body secondary-side tank boss hole.
6. Remove the snap ring while pushing the primary piston in to pre-
vent the piston from popping out.
7. Holding the primary piston rod, pull the primary piston assembly,
the plate, and the guide straight out.
8. Remove the plate and guide from the primary piston.
CAUTION:
When removing the plate from the primary piston rod, make
sure the inside of the plate does not damage the rod.
9. Tap flange using a soft block such as wood, and carefully pull
the secondary piston assembly straight out to prevent cylinder
inner wall from being damaged.

5. Cover the primary piston rod with cloth to prevent it getting dam-
aged, and attach the snap ring with the primary piston pushed
in.
CAUTION:

Make sure the area around the snap ring is snug in the
cylinder body bore groove.

Do not reuse the snap ring.
6. Place the side of the cylinder body with chamfering around the
pin insertion hole up, and secure the cylinder body flange sec-
tion with a vise.

2. After adjusting “B”, temporarily tighten the lock nut to install the
booster assembly to the vehicle. At this time, make sure to
install a gasket between the booster assembly and the vehicle.
3. Connect the brake pedal with the clevis of the input rod.
4. Install the pedal bracket mounting nuts and tighten them to the
specified torque.

WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne
particles or other materials.
CAUTION:

While removing cylinder body, do not depress brake pedal because piston will pop out.

It is not necessary to remove torque member mounting bolts on torque member 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.

Always replace shim and shim covers as a set when replacing brake pads.

Keep disc rotor clean of brake fluid.

Burnish the brake pads and disc rotor mutually contacting surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low mileage. Refer to BR-38, "
Brake
Burnishing Procedure" .

Refer to BR-30, "
HOW TO APPLY GREASE TO THE BRAKE PAD" for how to apply grease to brake pads.
WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne
particles or other materials.
CAUTION:

While the brake pad and cylinder body are separated, the piston may suddenly jump out, so do not
depress the brake pedal.

Apart from caliper assembly, disassembly or replacement, there is no need to remove caliper bolts
or brake hose or tube.

Do not damage piston boot.

Removal and Installation of Brake Pad (Other than Brembo Calipers)NFS000AU
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove lower sliding pin bolt.
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 (shown in the
figure) so as not to deform it.

Do not damage piston boot.

Keep disc rotor clean of brake fluid.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based
grease between pad retainer and pad.
2. Install pad retainers and pad assemblies to torque member.
CAUTION:
Inner pad and outer pad have pad-return mechanism on
upper side of pad retainer. When installing pad to torque
member, be sure to install pad return lever to pad wear sen-
sor securely.
3. Install cylinder body to torque member.
CAUTION:
When replacing pads with new ones, press in piston until
pads can be installed. In this case, carefully monitor brake fluid level in reservoir tank because
brake fluid will return to master cylinder reservoir tank.
4. Install lower sliding pin bolt, and tighten it to the specified torque. Refer to BR-27, "
Components" .
5. Secure disc rotor with wheel nuts. Depress brake pedal a few times until it gets a responsive touch.
6. Check front disc brake for drag.
7. Install tires to vehicle.

Removal and Installation of Brake Pad (With Brembo Calipers)NFS0000W
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove the clip from the pad pin.
3. Remove the pad pin while holding down the cross spring, then
remove the cross spring from the caliper.
4. Using pliers, remove the pad from the caliper.
HOW TO APPLY GREASE TO THE BRAKE PAD
Pad Side
Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease
about 0.5 g (0.018 oz) per surface equally to back plate side of Inner
Pad and Outer Pad. (Refer to the figure.)
CAUTION:
Make sure no foreign matter attaches itself to the grease.
INSTALLATION
1. Insert the piston to the position where the pad is attached.
NOTE:
Using a disc brake piston tool (commercial service tool), etc., makes it easier to push in the piston.
CAUTION:
By pushing in the piston, the brake fluid returns to the master cylinder reservoir tank. Watch the
level of the surface of the reservoir tank.
