BRAKE FLUID LEVEL
• Check that the fluid level in the reservoir tank is within the specified
range (MAX – MIN lines).
• Visually check for any brake fluid leakage around the reservoir
tank.
• Check the brake system for any leakage if the fluid level is
extremely low (lower than MIN).
• Check the brake system for fluid leakage if the warning lamp
remains illuminated even after the parking brake is released.
BRAKE LINE
1.
Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.
2.
Check for fluid leakage by fully depressing brake pedal while
engine is running.
CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
Draining
INFOID:0000000010305344
CAUTION:
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with water if it gets on a painted surface.
• Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-
nector or the battery negative terminal before draining.
1.
Connect a vinyl tube to the bleed valve.
2.
Depress the brake pedal and loosen the bleeder valve to gradu-
ally discharge brake fluid.
Refilling
INFOID:0000000010305345
CAUTION:
Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) connec-
tor or the battery negative terminal before refilling.

BRAKE FLUID
1.
Check that there is no foreign material in the reservoir tank, and
refill with new brake fluid.
CAUTION:
Never reuse drained brake fluid.
2.
Loosen the bleeder valve, slowly depress the brake pedal to the
full stroke, and then release the pedal. Repeat this operation at
intervals of 2 or 3 seconds until all brake fluid is discharged.
Then close the bleeder valve with the brake pedal depressed.
Repeat the same work on each wheel.
3.
Perform the air bleeding. Refer to
Bleeding Brake System
INFOID:0000000010305346
CAUTION:
• Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-
nector or the battery negative terminal before performing the work.
• Monitor the fluid level in the reservoir tank during the air bleeding.
• Always use new brake fluid for refilling. Never reuse the drained brake fluid.
1.
Connect a vinyl tube to the bleeder valve of the rear right brake.
2.
Fully depress the brake pedal 4 to 5 times.
3.
Loosen the bleeder valve and bleed air with the brake pedal depressed, and then quickly tighten the
bleeder valve.
4.
Repeat steps 2 and 3 until all of the air is out of the brake line.
In case of EPB rear caliper, operate parking brake 5 times to bleed the air.
5.
Tighten the bleeder valve to the specified torque. Refer to
BR-37, "BRAKE CALIPER ASSEMBLY :
(front disc brake),
BR-43, "BRAKE CALIPER ASSEMBLY : Exploded View"
(rear disc
brake).
6.
Perform steps 1 to 5 for the rear right brake
→
front left brake
→
rear left brake
→
and front right brake in
order.
7.
Check that the fluid level in the reservoir tank is within the specified range after air bleeding. Refer to

OPERATION
Depress the brake pedal several times at 5-second intervals with the
engine stopped. Start the engine with the brake pedal fully
depressed. Check that the clearance 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. This is a normal phenomenon due to
the brake system operation.
AIR TIGHT
• Idle the engine for 1 minute to apply vacuum to the brake booster,
and stop the engine. Then depress the brake pedal several times
at 5-second intervals until the accumulated vacuum is released to
atmospheric 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. This is a normal phenomenon due
to the brake system operation.
