BRAKE PEDALPFP:46501
Inspection and AdjustmentNFS000LS
PLAY AND CLEARANCE BETWEEN BRAKE PEDAL AND FLOOR PANEL WITH PEDAL
DEPRESSED
1. Check brake pedal height from dash lower panel.
2. Adjust height referring to the following specifications.
ADJUSTMENT
1. Loosen stop lamp switch and ASCD cancel switch (or brake switch) by rotating it counterclockwise by 45 °.
2. Loosen lock nut “A” on input rod, then rotate input rod to set pedal to the specified height, and tighten lock nut “A”. Refer to
BR-15, "
Components" .
CAUTION:
Make sure the threaded end of input rod stays inside clevis.
3. With pedal pulled and held by hand, press stop lamp switch and ASCD cancel switch (or brake switch) until its threaded end con-
tacts stopper rubber.
4. With the threaded end of stop lamp switch and ASCD cancel switch (or brake switch) contacting stopper rubber, rotate switch
clockwise by 45 ° to secure.
CAUTION:
Make sure that the clearance “C” between stopper rubber
and threaded end of stop lamp switch and ASCD cancel
switch (or brake switch) is within the standard.
5. Check pedal play. CAUTION:
Make sure that stop lamps go off when pedal is released.
6. Start engine to check brake pedal depressed height.
H Brake pedal height (from dash
lower panel top surface) 161.5
− 171.5 mm (6.358 − 6.752 in)
D Depressed pedal height [under a
force of 490 N (50 kg, 110 lb) with
engine running] More than 95 mm (3.74 in)
C Clearance between stopper rubber
and the threaded end of stop lamp
switch and ASCD cancel switch (or
brake switch) 0.74
− 1.96 mm (0.0291 −0.0772 in)
A Pedal play 3 − 11 mm (0.12 − 0.43 in)

BRAKE PEDAL
Revision: 2006 December 2006 FX35/FX45
INSPECTION AFTER REMOVAL
Make sure the rivets in the upper part of brake pedal are not
deformed.
Make sure that joint length “L” of sub-bracket and sliding plate is
5.5 mm (0.217 in) or more.
Replace brake pedal assembly if any non-standard condition is
detected.
Check clevis pin and plastic stopper for damage and deforma-
tion. Replace clevis pin if there are.
INSTALLATION
Installation in the reverse order of removal.
After installing brake pedal assembly to the vehicle, adjust brake pedal height. Refer to BR-6, "Inspection
and Adjustment" .

LEVEL CHECK
Make sure the fluid level in reservoir tank is within the standard
(between MAX and MIN lines).
Visually check around reservoir tank for fluid leakage.
If fluid level is excessively low, check brake system for leakage.
Release parking brake pedal and see if brake warning lamp
goes off. If not, check brake system for fluid leakage.
Drain and RefillNFS000LV
CAUTION:
Refill with new brake fluid “DOT3”.
Do not reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe it off and them wash it away with water
immediately.
Before servicing, disconnect actuator connector or battery cables.
1. Connect a vinyl tube to each bleed valve.
2. Depress brake pedal, loosen each bleed valve, and gradually remove brake fluid.
3. Make sure there is no foreign material in reservoir tank, and refill with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress pedal until it stops. Tighten bleed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.
5. Bleed Air. Refer to BR-10, "
Bleeding Brake System" .

Bleeding Brake SystemNFS000LW
CAUTION:
Carefully monitor brake fluid level in reservoir tank
during bleeding operation.
Refill with new brake fluid “DOT 3”. Make sure it is at least
half way at all times while bleeding air out of system.
Place a container under master cylinder not to spill brake
fluid.
Turn ignition switch OFF and disconnect VDC actuator
connectors or battery cables.
Bleed air in the following order. Right rear brake → Left
front brake → Left rear brake → Right front brake
1. Connect a transparent vinyl tube to bleed valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open bleed valve to release air.
4. Close bleed valve.
5. Release brake pedal slowly.
6. Repeat steps 2, through 5, until clear brake fluid comes out of bleed valve.

CAUTION:
All brake hoses and tubes must be free from excessive bending, twisting and pulling.
Make sure there is no interference with other parts when turning steering both clockwise and
counterclockwise.
The brake tubes and hoses is an important safety part. If a brake fluid leak is detected, always dis-
assemble the parts. Replace applicable part with a new one, if necessary.
Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe it off and them wash it away with water
immediately.
Do not bend or twist brake hose sharply, or strongly pull it.
When removing components, cover brake line connections so that no dirt, no dust, or other for-
eign matter gets in.
Refill with new brake fluid “ DOT 3 ”.
Do not reuse drained brake fluid.
Removal and Installation of Front Brake Tube and Brake Hose NFS000LY
REMOVAL
