Brake Diagnosis Note

Road Test for 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 flow table for other causes.

Brakes Symptom Diagnosis

Condition
Not enough braking force Brake fluid leakage

Diagnostic Information and Procedures

S6JB0A4104001
Possible cause
Brake disc or pads stained with fluid
Overheated brakes
Poor contact of brake shoes on brake
drum
Brake shoes stained with fluid or wet
with water
Badly worn brake shoe linings
Defective wheel cylinders
Malfunctioning caliper assembly
Air in system
Malfunctioning ABS (ESP®)
Brake Fluid Inspection
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.
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 cap.
CAUTION
!
Since brake system of this vehicle is factory
filled with brake fluid indicated on reservoir
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.
