Diagnosis
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 end 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 leak-
age. If even a slight evidence of leakage is noted, the cause should be corrected or defective parts should be
replaced.
If fluid level is lower than the minimum level of reservoir, refilling is necessary. Fill reservoir with specified brake
fluid.
Brake fluid: Refer to reservoir tank cap.
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
in the hydraulic system to deteriorate.
If primary piston cups are swollen, then rubber parts have deteriorated. This deterioration may also be evi-
denced by swollen wheel cylinder piston cups on the drum brake wheels.
If deterioration of rubber is evident, disassemble all hydraulic parts and wash with alcohol. Dry these parts with
compressed air before assembly to keep alcohol out of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake mechanisms, check for fluid on the linings. If excessive fluid is
found, replace the linings.
If master cylinder piston seals are satisfactory, check for leakage or excessive heat conditions. If condition is not
found, drain fluid, flush with brake fluid, refill and bleed the system.
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.CAUTION:
Since brake system of this vehicle is factory-filled with brake fluid indicated on reservoir tank cap, do
not use or mix different type of fluid when refilling; otherwise serious damage will occur.
Do not use old or used brake fluid, or any fluid from a unsealed container.

Rear Drum Brake Shoe Adjustment
Rear brake has self-adjusting mechanism but it does require
adjustment for proper drum to shoe clearance when brake shoe
has been replaced or brake drum has been removed for some
other service.
Adjustment is automatically accomplished by depressing brake
pedal about 30 times with approximately 30 kg (66 Ibs) load after
all parts are installed.
Then check brake drum for dragging and brake system for proper
performance. After lowering vehicle from hoist, brake test should
be performed.
Parking Brake Inspection and Adjustment
INSPECTION
Hold center of parking brake lever grip and pull it up with 20 kg
(44 Ibs) force.
With parking brake lever pulled up as above, count ratchet
notches.
There should be 6 to 8 notches.
Also, check if both right and left rear wheels are locked firmly. To
count number of notches easily, listen to click sounds that ratchet
makes while pulling parking brake lever without pressing its but-
ton.
One click sound corresponds to one notch.NOTE:
Be sure to use particular brake fluid either as indicated
on reservoir cap of that vehicle or recommended in
owner’s manual which comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked
on reservoir.
When brake warning lamp lights sometimes during driv-
ing, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake system for
leakage.
Correct leaky points and then refill to specified level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has
been used for mineral oil or a container which is wet from
water. Mineral oil will cause swelling and distortion of
rubber parts in hydraulic brake system and water mixed
into brake fluid will lower fluid boiling point. Keep all fluid
containers capped to prevent contamination.

Scan tool data definitions
FUEL SYSTEM (FUEL SYSTEM STATUS)
Air / fuel ratio feedback loop status displayed as either open or closed loop. Open indicates that ECM ignores
feedback from the exhaust oxygen sensor.
Closed indicates final injection duration is corrected for oxygen sensor feedback.
CALC LOAD (CALCULATED LOAD VALUE, %)
Engine load displayed as a percentage of maximum possible load. Value is calculated mathematically using the
formula : actual (current) intake air volume ÷ maximum possible intake air volume x 100%.
COOLANT TEMP. (ENGINE COOLANT TEMPERATURE, °C, °F)
It is detected by engine coolant temp. sensor
SHORT FT B1 (SHORT TERM FUEL TRIM, %)
Short term fuel trim value represents short term corrections to the air / fuel mixture computation. A value of 0
indicates no correction, a value greater than 0 means an enrichment correction, and a value less than 0 implies
an enleanment correction.
LONG FT B1 (LONG TERM FUEL TRIM, %)
Long term fuel trim Value represents long term corrections to the air / fuel mixture computation. A value of 0 indi-
cates no correction, a value greater than 0 means an enrichment correction, and a value less than 0 implies an
enleanment correction.
MAP (INTAKE MANIFOLD ABSOLUTE PRESSURE, kPa, inHg)
It is detected by manifold absolute pressure sensor and used (among other things) to compute engine load.
ENGINE SPEED (rpm)
It is computed by reference pulses from crankshaft position sensor.
VEHICLE SPEED (km/h, MPH)
It is computed based on pulse signals from vehicle speed sensor.
IGNITION ADVANCE (IGNITION TIMING ADVANCE FOR NO.1 CYLINDER, °)
Ignition timing of NO.1 cylinder is commanded by ECM. The actual ignition timing should be checked by using
the timing light.
INTAKE AIR TEMP. (°C, °F)
It is detected by intake air temp. sensor and used to determine the amount of air passing into the intake manifold
as air density varies with temperature.
MAF (MASS AIR FLOW RATE, gm/s, lb/min)
It represents total mass of air entering intake manifold which is computed based on signals from MAP sensor,
IAT sensor, TP sensor, etc.BRAKE SWIgnition switch
