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-14, "
Component".
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 low-
er 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)

OPERATING CHECK
With engine stopped, change the vacuum to the atmospheric pres-
sure by depressing brake pedal several times. Then with brake
pedal fully depressed, start engine and when the vacuum pressure
reaches the standard, make sure the clearance between brake pedal
and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIRTIGHT CHECK
 Run engine at idle for approximately 1 minute, and stop it afterapplying vacuum to booster. Depress brake pedal normally to
change the vacuum to the atmospheric pressure. Make sure dis-
tance between 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 brake pedal is interval is approximately at intervals
5 seconds.
