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.

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 BR-10, "
Bleeding Brake System".
Bleeding Brake SystemINFOID:0000000003811176
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 sub 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.
5. Tighten the bleeder valve to the specified torque.
 Front disc brake: refer to BR-34, "
BRAKE CALIPER ASSEMBLY : Exploded View".
 Rear disc brake: refer to BR-40, "
BRAKE CALIPER ASSEMBLY : Exploded View".
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 sub tank is within the specified range after air bleeding. Refer to BR-9,
"Inspection".

REMOVAL
CAUTION:
Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with wate r if it gets on a painted surface.
1. Remove tires.
2. Drain brake fluid. Refer to BR-9, "
Draining".
3. Loosen the flare nut with a flare nut wrenc h and separate the brake tube from the hose.
CAUTION:
 Never scratch the flare nut and the brake tube.
 Never bend sharply, twist or strong ly pull out the brake hoses and tubes.
 Cover open end of brake tub es and hoses when disconnecting to prevent entrance of dirt.
4. Remove the union bolt and copper washers, and remove the brake hose from the brake caliper assembly.
5. Remove the lock plate and remove the brake hose.
INSTALLATION
CAUTION:
Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with wate r if it gets on a painted surface.
1. Assemble the union bolt and the copper washers to the brake hose. CAUTION:
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.
