INSPECTION
Brake Pedal Height
Check the brake pedal height (H1) between the dash lower panel (1)
and the brake pedal upper surface.
CAUTION:
Remove the floor trim.
Stop Lamp Switch and ASCD Brake Switch
Check the clearance (C) between stopper rubber (1) and stop lamp
switch and ASCD brake switch (2) threaded end.
CAUTION:
The stop lamp must be turned off when the brake pedal is
released.
NOTE:
Pull the brake pedal pad to make the clearance between stopper
rubber and stop lamp switch and ASCD brake switch threaded end.
Brake Pedal Play
Press the brake pedal. Check the brake pedal play (A).
Depressed Brake Pedal Height
Check the brake pedal height (H2) between the dash lower panel (1)
and the brake pedal upper surface when depressing the brake pedal
at 490 N (50 kg, 110 lb) while turning engine ON.
CAUTION:
Remove the floor trim.Standard

BRAKE FLUID
InspectionINFOID:0000000003811173
BRAKE FLUID LEVEL
 Check that the fluid level in the sub tank is within the specified
range (MAX – MIN lines).
 Visually check for any brake fluid leakage around the sub tank,
reservoir tank and hose.
 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.
DrainingINFOID:0000000003811174
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.
RefillingINFOID:0000000003811175
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.
1. Check that there is no foreign material in the sub tank, and refill with new brake fluid.
CAUTION:
Never reuse drained brake fluid.

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.

Never reuse the copper washer.
2. Align the brake hose pin to the projection (A) of the brake caliper assembly and tighten the union bolt (1) to the specified torque.
3. Install the brake tube to the brake hose, temporarily tighten the flare nut by hand until it does not rotate further, and fix the brake
hose to the bracket with the lock plate.
CAUTION:
Check that all brake hoses and tubes are not twisted and
bent.
4. Tighten the flare nut to the specified torque with a crowfoot and torque wrench.
CAUTION:
Never scratch the flare nut and the brake tube.
5. Refill with new brake fluid and perform the air bleeding. Refer to BR-10, "
Bleeding Brake System".
CAUTION:
Never reuse drained brake fluid.
FRONT : InspectionINFOID:0000000003811189
INSPECTION AFTER INSTALLATION
1. Check the brake hoses and tubes for the following: no scratches; no twist and deformation; no interfer-
ence with other components when steering the steering wheel; no looseness at connections.
2. Depress the brake pedal with a force of 785N (80 kg, 177 lb) and hold down the pedal for approximately 5
seconds with the engine running. Check for any fluid leakage.
CAUTION:
Retighten the applicable connect ion to the specified torque and repair any abnormal (damaged,
worn or deformed) part if any brake fluid leakage is present.
