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.

Condition Possible Cause Correction
Not enough braking
forceBrake oil leakage from brake lines Locate leaking point and repair.
Brake disc or pads stained with oil Clean or replace.
Overheated brakes Determine cause and repair.
Poor contact of shoes on brake drum Repair for proper contact.
Brake shoes linings stained with oil or wet with
waterReplace.
Badly worn brake shoe linings Replace.
Defective wheel cylinders Repair or replace.
Malfunctioning caliper assembly Repair or replace.
Air in system Bleed system.
Maladjusted sensor spring length of LSPV Check or adjust.
Broken sensor spring of LSPV Replace.
Defective collar of LSPV Replace.
Malfunctioning ABS (Antilock brake system), if
equippedCheck system and replace as nec-
essary.
Brake pull (Brakes not
working in unison)Pad or shoe linings are wet with water or
stained with oil in some brakesReplace.
Drum-to-shoe clearance out of adjustment in
some brakes (Malfunctioning auto adjusting
mechanism)Check for inoperative auto adjusting
mechanism.
Drum is out of round in some brakes Replace.
Wheel tires are inflated unequally Inflate equally.
Malfunctioning wheel cylinders Repair or replace.
Disturbed front wheel alignment Adjust as prescribed.
Unmatched tires on same axle Tires with approximately the same
amount of tread should be used on
the same axle.
Restricted brake tubes or hoses Check for soft hoses and damaged
lines.
Replace with new hoses and new
double-walled steel brake tubing.
Malfunctioning caliper assembly Check for stuck or sluggish pistons
and proper lubrication of caliper
slide bush.
Loose suspension parts Caliper should slide.
Check all suspension mountings.
Loose calipers Check and torque bolts to specifica-
tions.
Noise (high pitched
squeak without brake
applied)Front lining worn out Replace brake pads.
Rear brake locked pre-
maturelyMaladjusted sensor spring length of LSPV Check or adjust.
Malfunctioning LSPV assembly Replace assembly.

(For vehicles
equipped with ABS)Malfunctioning ABS, if equipped Check system and replace as nec-
essary.
