Inspection and AdjustmentNFS00006
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)
A/T models : 161.5 – 171.5 mm (6.36 – 6.75 in)
Depressed pedal height “H

kg, 110 lb) with the engine running]
M/T models : More than 90 mm (3.54 in)
A/T models : More than 95 mm (3.74 in)
Clearance “C ” between threaded end of the stop lamp
switch/ASCD cancel switch (2) and stopper rubber (3).
: 0.74 – 1.96 mm (0.0291 – 0.0772 in)
Pedal play “A” : 3 – 11 mm (0.12 – 0.43 in)

On-Vehicle InspectionNFS0000L
OPERATING CHECK
With the engine stopped, change the vacuum to the atmospheric
pressure by depressing the brake pedal several times. Then with
brake pedal fully depressed, start the engine and when the vacuum
pressure reaches the standard, check that the clearance between
the brake pedal and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIRTIGHT CHECK
Run the engine at idle for approximately 1 minute, and stop it
after applying vacuum to the booster. Depress the brake pedal
normally to change the vacuum to the atmospheric pressure.
Check that distance between the brake pedal and floor panel
gradually increases.
Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change after
holding pedal down for 30 seconds.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
