PRECAUTIONS
Revision: 2006 November2007 350Z
Use flare nut crowfoot and torque wrench when removing and
installing brake tube.
When installing brake piping, be sure to check torque.
Before working, turn the ignition switch OFF and disconnect the
connectors of ABS actuator and control unit or the battery nega-
tive terminal.
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-38, "
Brake Burnishing Procedure" .
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.SBR686C

PLAY AND CLEARANCE BETWEEN THE BRAKE PEDAL AND FLOOR PANEL WITH PEDAL
DEPRESSED
1. Check the brake pedal free height from the dash lower panel (1).
2. Adjust the height referring to the following specifications.
ADJUSTMENT
1. Loosen the stop lamp switch and ASCD cancel switch by rotat-
ing it counterclockwise by 45°.
2. Loosen the lock nut (A) on the input rod, then rotate the input
rod to set the pedal to the specified height, and tighten the lock
nut (A) to the specified torque. Refer to BR-23, "
Components" .
CAUTION:
Check that the threaded end of the input rod stays inside
the clevis.
3. With the pedal pulled and held by hand, press the stop lamp
switch and ASCD cancel switch until its threaded end contacts
the stopper rubber.
4. With the threaded end of the stop lamp switch contacting the
stopper rubber and ASCD cancel switch, rotate the switch clock-
wise by 45° to secure.
CAUTION:
Make sure that the clearance “C” between the stopper rub-
ber and threaded end of the stop lamp switch and ASCD
cancel switch is within the standard.
5. Check the pedal play.
CAUTION:
Make sure that the stop lamps go off when the pedal is
released.
6. Start the engine to check the brake pedal's depressed height.Brake pedal height “H
1 ” (from dash lower panel top sur-
face)
M/T models : 153.2 – 163.2 mm (6.03 – 6.43 in)

CAUTION:
While bleeding, pay attention to master cylinder fluid level.
1. Before working, turn the ignition switch OFF and disconnect the connectors of ABS actuator and control
unit or battery negative terminal.
2. Connect a vinyl tube to the rear right bleed valve.
3. Fully depress brake pedal 4 to 5 times.
4. With the brake pedal depressed, loosen the bleed valve to let the air out, and then tighten it immediately.
5. Repeat steps 3, 4 until no more air comes out.
6. Tighten the bleed valve to the specified torque. Refer to BR-27, "
Components" (Front) and BR-40, "Com-
ponents" (Rear).
7. In steps 2 to 6 below, with the master cylinder reservoir tank filled at least half way, bleed air from the front

When removing components, cover connections so that no dirt, dust, or other foreign matter gets
in.
Refill with new brake fluid “ DOT 3 ”.
Do not reuse drained brake fluid.

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.
