CHECKING BRAKE FLUID LEVEL
lMake sure the fluid level in the tank is within the standard
(between MAX and MIN lines).
lVisually check around the reservoir tank for fluid leakage.
lIf fluid level is excessively low, check brake system for fluid leak-
age.
lRelease parking brake lever and see if brake warning lamp goes
off. If not, check brake system for fluid leakage.
Drain and RefillEFS005SJ
CAUTION:
lRefill with new brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, immediately wipe off them and wash it away with water.
lBefore working, disconnect connector of ABS actuator and electric unit (control unit) or the bat-
tery cables.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke
and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the pedal. Repeat the same work for each
wheel.
5. Bleed air. Refer toBR-11, "
Bleeding Brake System".

Bleeding Brake SystemEFS005SK
CAUTION:
lWhile bleeding, pay attention to master cylinder fluid level.
lBefore working, disconnect electrical connector of ABS actuator and electric unit (control unit) or
the battery cable from the negative terminal.
LHD MODEL
1. Connect a vinyl tube to the rear right bleed valve.
2. Fully depress brake pedal 4 to 5 times.
3. With brake pedal depressed, loosen bleed valve to let the air out, and then tighten it immediately.
4. Repeat steps 3, 4 until no more air comes out.
5. Tighten bleed valve to specified torque. Refer toBR-24, "
Components"(front disc brake),BR-30, "Com-
ponents"(rear drum brake).
6. From the steps 1 to 5 above, with master cylinder reservoir tank filled at least half way, bleed air from the
front left, rear left, and front right brake, in that order.
RHD MODEL
1. Connect a vinyl tube to the rear left bleed valve.
2. Fully depress brake pedal 4 to 5 times.
3. With brake pedal depressed, loosen bleed valve to let the air out, and then tighten it immediately.
4. Repeat steps 3, 4 until no more air comes out.
5. Tighten bleed valve to specified torque. Refer toBR-24, "

CAUTION:
lAll brake tubes and hoses must be free from excessive bending, twisting and pulling.
lMake sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.
lBrake tube and hose is an important safety part. Always disassemble the parts and retighten their
fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part is
detected.
lBe careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe off them and wash it away with water.
lDo not bend or twist brake hose sharply, or strongly pull it.
lCover the open end of brake tube and hoses when disconnecting to prevent entrance of dirt.
lRefill with new brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
Removal and Installation of Front Brake Tube and Brake HoseEFS005SM
REMOVAL
1. Drain brake fluid. Refer toBR-10, "Drain and Refill".
2. Using a flare nut wrench, disconnect brake tube from brake hose.
3. Remove union bolt and remove brake hose from caliper assembly.
4. Remove lock plate and remove brake hose from vehicle.
INSTALLATION
1. Assemble the union bolt and copper washers to the brake hose.
2. Insert brake hose by aligning with the protrusion on caliper
assembly, and tighten union bolt to the specified torque. Refer to
BR-12, "
Hydraulic Circuit".
3. Connect brake hose to the brake tube, partially tighten the flare
nut as much as possible by hand, then secure it to the bracket
with lock plate.
4. Using flare nut torque wrench, tighten flare nut to the specified
torque. Refer toBR-12, "
Hydraulic Circuit".
5. Refill brake fluid and bleed air. Refer toBR-11, "
Bleeding Brake
System".
Removal and Installation of Rear Brake Tube and Brake HoseEFS005SN
REMOVAL

2. Using a flare nut wrench, disconnect brake tube from brake hose, wheel cylinder and load sensing valve.
3. Remove lock plate and remove brake tube from vehicle.
INSTALLATION
1. Insert brake tube, then secure it to bracket with lock plate.
2. Install brake tube to brake hose, wheel cylinder and load sensing valve, then tighten the flare nut to the
specified torque using a flare nut torque wrench. Refer toBR-12, "
Hydraulic Circuit".
3. Refill brake fluid and bleed air. Refer toBR-11, "
Bleeding Brake System".

Inspection after Installation
EFS005SO
CAUTION:
Brake tubes and hoses are important safety parts. Always disassemble the parts and retighten their fit-
tings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part is
detected.
1. Check hydraulic brake lines (tubes and hoses) and connections for fluid leakage, damage, twists, defor-
mations, contacts with other parts, and loose connections. Replace any damage parts.
2. While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running at idle speed for
approximately 5 seconds, check each part for fluid leakage.

Inspection
EFS006A8
INSPECTION
1. With the vehicle in unladen condition, a person should sit in driver's seat at the rear. Then he/she should
get out of car gently. (This is to stabilize suspension deflection.)
NOTE:
“Unladen condition”: with full coolant, lubricant, 6 to 8 litters of fuel, spare tyre, jack, and hand tools
loaded.
2. Press load sensing valve against stopper bolt. Check if center-to-center length “L” between adjusting ref-
erence hole and reference pin is as specified below.
lIf measurement is outside the standard, perform following;
loosen mounting bolt of sensor spring bracket. By moving
sensor spring bracket, adjust so that the length “L” comes into
specified range.
3. Connect brake fluid pressure tester (special service tool) to
bleed valves of front caliper and rear wheel cylinder.
4. Bleed air from brake fluid pressure tester (special service tool).
5. With brake pedal depressed, check brake fluid pressure at front
caliper and rear wheel cylinder. The respective measurements
should be as specified in the table below.
6. Under condition of step 2 above, adjust rear shaft weight with
weights to obtain 143.9-146.9 mm (5.67-5.78 in) as length
“L”. Then, check brake fluid pressure as described in step 5
above. If measurements are outside the standards, replace load
sensing valve main body.

7. After inspection, remove brake fluid pressure tester (special service tool) and bleed air. Refer toBR-11,
"Bleeding Brake System". Length “L” : 143.9-146.9 mm (5.67-5.78 in)
