Rear Brake Hose / Pipe ConstructionS7RS0B4101003
Diagnostic Information and Procedures
Brakes Diagnosis NoteS7RS0B4104001
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 vari ous 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 fl
uid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low leve l indicates a leak in the
system. In such a case, chec k the entire brake system
for leakage. If even a slight ev idence 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 in
the hydraulic system to deteriorate.

Downloaded from www.Manualslib.com manuals search engine Brake Control System and Diagnosis: 4A-5
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 pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
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.

Repair Instructions
Brake Pedal ComponentsS7RS0B4106019
CAUTION!
Never disassemble brake pedalassembly.
Disassemble will spoil its originalfunction. If
faulty condition is found, replaceit with new
one.

Brake Pedal Free Height InspectionS7RS0B4106001
1) Check brake pedal free height. If it is not within specification, check and ad just following item 2) and
6).
Brake pedal free height “a” from carpet
130 – 150 mm (5.1 – 5.9 in.) 2) Check measurement between booster mounting
surface and center of clevis pin hole. When booster
push rod clevis has been reinstalled, it is important
that the measurement is adj usted (refer to “Brake
Booster Inspection and Adjustment”).
3) Check stop light switch position . Adjust it if it is out of
specification.
4) Check pedal for dent.
5) Check brake booster for installation.
6) Check brake booster push rod for length.
Brake Pedal Play InspectionS7RS0B4106002
Pedal play should be within the following specification. If
out of specification, check stop light switch for proper
installation position and adjust if necessary.
Also check pedal shaft bolt and booster clevis pin
installation for looseness and replace if defective.

Excessive Pedal Travel InspectionS7RS0B4106003
1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 300 N (30 kg, 66 lbs) load, measure brake pedal to wall
(dash panel silencer) clearance “a”. If clearance “a”
is less than specification, the most possible cause is
air in lines. Should clearance “a” remain less than
specification even after bleeding of system, other
possible infrequent cause is booster push rod length
out of adjustment.
• Bleed brake system. Refer to “Air Bleeding of Brake System”.
Brake arm pedal to wall clearance “a”
When pedal depressed at 300 N (30 kg, 66 lbs):
over 75 mm (2.95 in.)
Brake Fluid Level InspectionS7RS0B4106004
1) Check master cylinder, reservoir and reservoir hose (if equipped) for crack, damage and brake fluid
leakage. If any faulty condition exists, correct or
replace.
2) Check that brake fluid level is between MAX and MIN marks on reservoir.
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 driving, replenis h 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.

Stop Light Switch AdjustmentS7RS0B4106005
Adjustment should be made as follows. Pull up brake
pedal toward you and while holding it there, adjust
switch position so that clea rance between end of thread
and brake pedal is as specified. Then lock it by turning
clockwise.
Clearance between brake pedal and stop light switch
“a”: 1.2 – 2.2 mm (0.05 – 0.08 in.)
