BRAKE PEDAL

BRAKE PEDALPFP:46501
Inspection and AdjustmentBFS000BG
Play and clearance inspection between brake pedal and floor panel with pedal depressed.

Check brake pedal height from dash lower panel (1).

Adjust height referring to the following specifications.
ADJUSTMENT
1. Loosen stop lamp switch, brake switch and/or ASCD cancel
switch by turning it counterclockwise by 45°.
2. Loosen lock nut “A” on input rod, then rotate input rod to set,
brake pedal to the specified height, and tighten lock nut “A”.
Refer to BR-22, "
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,
brake switch and/or ASCD cancel switch until its threaded end
contacts bracket.
4. With threaded end of stop lamp switch, brake switch and/or
ASCD cancel switch contacting bracket, rotate switch clockwise
by 45° to secure.
CAUTION:

Make sure that the clearance “C” between bracket and
end of stop lamp switch, brake switch and/or ASCD can-
cel switch is within the standard.

When locking stop lamp switch and ASCD cancel switch,
pull brake pedal to avoid moving toward the direction
where switches are being pressed.
5. Check the pedal play.
CAUTION:
Make sure that stop lamps goes off when pedal is released.
6. Start engine to check brake pedal depressed height.

Inspection After InstallationBFS000BO
CAUTION:
If leakage occurs around brake tube and hose connections, retighten or, if damaged part is detected,
replace the damage part.
1. Check brake hoses, brake tubes, and connections for fluid leakage, damage, twists, deformation, contact
with other parts, and loose connections.
2. While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running for approximately
5 seconds, check for fluid leak each part.

BRAKE BOOSTERPFP:47200
On-Board Inspection and ServiceBFS000BS
OPERATION 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 that clearance between brake
pedal and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIR TIGHT CHECK

Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change the vacuum to the atmospheric pressure. Make sure
distance between brake pedal and floor panel gradually
increases.

Depress brake pedal while engine is running, and stop engine
with brake pedal is depressed. Brake pedal stroke should not
change after holding brake pedal down for 30 seconds.
CAUTION:
Depressing brake pedal interval is approximately at intervals 5
seconds.
