BRAKE BOOSTER
InspectionINFOID:0000000009463686
OPERATION
Depress the brake pedal several times at five second intervals with
the engine stopped. Start the engine with the brake pedal fully
depressed. Check that the cl earance between brake pedal and dash
lower panel decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. Th is is normal brake system opera-
tion.
VACUUM INSPECTION
Idle the engine for one minute to apply vacuum to the brake booster.
Stop the engine. Depress the brake pedal several times at five sec-
ond intervals until the accumulated vacuum is released to atmo-
spheric pressure. Check that the clearance between brake pedal
and dash lower panel gradually increases (A → B → C) each time
the brake pedal is depressed during this operation.
Depress the brake pedal with the engine running. Then stop the
engine while holding down the brake pedal. Check that the brake
pedal stroke does not change after holding down the brake pedal for
30 seconds or more.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. Th is is normal brake system opera-
tion.

ADJUSTMENT
1. Loosen the stop lamp switch (2) and ASCD cancel switch (1) by turning each counterclockwise by 45 °.
2. Loosen clevis lock nut (1) on the input rod (2), then turn input rod to adjust the brake pedal height to specification. Tighten cle-
vis lock nut (1) to specification.
CAUTION:
• Check the height with the floor trim removed.
• The threaded end of the input rod (2) must project to the
inner side (L) of the clevis (3).
3. With the pedal pulled up and held by hand, press the stop lamp switch (1) and ASCD cancel switch (2) until the threaded end
contacts the brake pedal bracket.
4. With the threaded end of the stop lamp switch (1) and ASCD cancel switch (2) contacting the brake pedal bracket, rotate the
switch clockwise by 45 ° to secure.
CAUTION:
Make sure that the clearance (C) between brake pedal
bracket and end of stop lamp switch (1) and ASCD cancel
switch (2) is within the standard. Refer to BR-48, "Brake
Pedal".
5. Check the brake pedal for smooth operation. CAUTION:
Make sure that stop lamps are off when the brake pedal is released.

CAUTION:
• Do not spill or splash brake fluid on painted surf aces. Brake fluid may damage paint. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• Prior to repair, turn the ignition switch OFF, disconnect the ABS actuator and electric unit (control
unit) connector or negative battery terminal. Refer to PG-73, "Removal and Installation (Battery)"
.
• Refill brake system with new brake fluid. Refer to MA-11, "FOR USA AND CANADA : Fluids and
Lubricants".
• Do not reuse drained brake fluid.
DRAINING

tive battery terminal. Refer to PG-73, "Removal and Installation (Battery)"
.
2. Connect a vinyl tube to bleeder valve.
3. Depress brake pedal, loosen bleeder valve, and gradually remove brake fluid.
REFILLING
1. Make sure no foreign material is in the reservoir, and refill withnew brake fluid.
CAUTION:

2. Refill the brake system as follows: • Depress the brake pedal.
• Loosen bleeder valve.
• Slowly depress brake pedal to 2/3 of the brake pedal full
stroke.
• Tighten bleeder valve.
• Release brake pedal.
Repeat this operation at intervals of two or three seconds until
all old brake fluid is discharged. Add new brake flui d to master cylinder reservoir sub tank frequently.
