HVAC Air Filter (If Equipped) InspectionS6RW0D0206034
Check HVAC air filter for dirt and dust referring to “HVAC
Air Filter Inspection (If Equipped) in Section 7A”. If air
filter is dirty, clean or replace air filter with new one.
HVAC Air Filter (If Equipped) ReplacementS6RW0D0206035
Replace HVAC air filter with new one referring to “HVAC
Air Filter Removal and Installation (If Equipped) in
Section 7A”.
Final Inspection for Maintenance ServiceS6RW0D0206036
WARNING!
When carrying out road tests, select a safe
place where no man or no running vehicle is
seen so as to prevent any accident.
Seats
Check that seat slides smoothly and locks securely at
any position. Also check that reclining mechanism of
front seat back allows it to be locked at any angle.
Seat Belt
Inspect belt system including webbing, buckles, latch
plates, retractors and anchors for damage or wear.
Check that seat belt is securely locked. If “REPLACE
BELT” label on seat belt is visible, replace belt.
Battery Electrolyte Level Check
Check that the electrolyte level of all battery cells is
between the upper and lower level lines on the case. If
battery is equipped with built-in indicator, check battery
condition by the indicator.
Accelerator Pedal Operation
Check that pedal operates smoothly without getting
caught or interfered by any other part.
Engine Start
Check engine start for readiness.
WARNING!
Before performing the following check, be
sure to have enough room around the
vehicle. Then, firmly apply both the parking
brake and the regular brakes. Do not use the
accelerator pedal. If the engine starts, be
ready to turn off the ignition promptly. Take
these precautions because the vehicle could
move without warning and possibly cause
personal injury or property damage.
On automatic transaxle vehicles, try to start the engine in
each select lever position. The starting motor should
crank only in “P” (Park) or “N” (Neutral).
On manual transaxle vehicles, place the shift lever in
“Neutral,” depress clutch pedal fully and try to start.
Exhaust System Check
Check for leakage, cracks or loose supports.
Clutch (for Manual Transaxle)
Check for the following.
• Clutch is completely released when depressing clutch
pedal,
• No slipping clutch occurs when releasing pedal and
accelerating.
• Clutch itself is free from any abnormal condition.
Gearshift or Select Lever
Check gear shift or select lever for smooth shifting to all
positions and for good performance of transaxle in any
position.
With automatic transaxle equipped vehicle, also check
that shift indicator indicates properly according to which
position select lever is shifted to.
With automatic transaxle equipped vehicle, make sure
that vehicle is at complete stop when shifting select lever
to “P” range position and release all brakes.
Brake
Foot brake
Check the following:
• that brake pedal has proper travel,
• that brake works properly,
• that it is free from noise,
• that vehicle does not pull to one side when brake is
applied.
• and that brake do not drag.
Parking brake
Check that lever has proper travel.
WARNING!
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property
damage. Be prepared to apply regular brake
quickly even if vehicle should start to move.
Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and brake
lever is pulled all the way.

General Description
Brakes ConstructionS6RW0D4101001
When the foot brake pedal is depressed, hydraulic pressure is developed in the master cylinder to actuate pistons (two
in front and four in rear).
The master cylinder is a tandem master cylinder. Brake pipes are connected to the master cylinder and they make two
independent circuits. One connects front right & rear left brakes and the other connects front left & rear right brakes.
In this brake system, the disc brake is used for the front wheel brake and drum brake (leading / trailing shoes) for the
rear brake.
The parking brake system is mechanical. It applies brake force to only rear wheels by means of the cable and
mechanical linkage system. The same brake shoes of rear drum brake are used for both parking and foot brakes.
NOTE
• The figures show LH steering vehicle.
• The difference between RH steering vehicle and LH steering vehicle is the location of the brake
master cylinder, the brake booster and ABS hydraulic unit / control module assembly.

Diagnostic Information and Procedures
Brakes Diagnosis NoteS6RW0D4104001
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both light
and heavy pedal forces at various speeds to determine if
the vehicle stops evenly and effectively. Also drive
vehicle to see if it leads to one side or the other without
brake application. If it does, check the tire pressure, front
wheel alignment and front suspension attachments for
looseness. See diagnosis table for other causes.
Brake Fluid Leaks
Check the master cylinder fluid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low level indicates a leak in the
system. In such a case, check the entire brake system
for leakage. If even a slight evidence of leakage is noted,
the cause should be corrected or defective parts should
be replaced.Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may
cause the brake fluid to boil or the rubber components
(piston cups and brake hoses) in the hydraulic system to
deteriorate.
If the above fluid is included in the system, replace the
master cylinder assembly and other rubber components
(hoses). The master cylinder assembly is disassemble
parts to maintain the performance.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.
