< PRECAUTION >
PRECAUTIONS
• Tighten the brake tube flare nut to the specified torque with
crowfoot (A) and torque wrench (B).
• Always confirm the specified ti ghtening torque when install-
ing the brake pipes.
• Turn the ignition switch OFF and disconnect the ABS actuator
and electric unit (control unit) connector or the battery nega-
tive terminal before performing the work.
• Check that no brake fluid leakage is present after replacing the parts.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage.
- Front brake: refer to BR-16, "Brake Burnishing"
.
- Rear brake: refer to BR-17, "Brake Burnishing"

BRAKE FLUID LEVEL
• Make sure that the brake fluid level in the reservoir tank is betweenthe MAX and MIN lines.
• Visually check around the reservoir tank for brake fluid leakage.
• If the brake fluid level is excessively low, check the brake system for leakage.
• If brake warning lamp remains illuminated after parking brake pedal is released, check the brake system for brake fluid leakage.
BRAKE LINE
1. Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.
2. Check for brake fluid leakage by depressing brake pedal under a force of 785 N (80 kg-f, 177 lb-f) for approximately 5 seconds
while engine is running.
CAUTION:
If brake fluid leakage occurs around joints, retighten or
replace damaged parts as necessary.

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.

APPEARANCE
Check surface of disc rotor for uneven wear, cracks or damage. Replace if any abnormal conditions exist.
RUNOUT
1. Check the wheel bearing axial end play before the inspection. Refer to FAX-6, "Inspection".
2. Secure the disc rotor to the wheel hub and bearing assembly with wheel nuts at two wheel nut locations.
3. Inspect the runout with a dial gauge, measured at 10 mm (0.39 in) inside the disc edge.
4. Find the installation position with a minimum runout by shifting the disc rotor-to-wheel hub and bearing assembly installation
position by one hole at a time if the runout exceeds the limit
value.
5. Refinish the disc rotor if the runout is outside the limit even after performing the above operation. When refinishing, use Tool.

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.
