Brake Pedal Foot Protection System Construction (If Equipped)

Should a front crash occur and the engine push the dash panel toward the interior side, the brake pedal bracket is also
pushed toward the interior side. In this case, the brake pedal lever comes off from the brake pedal, thereby preventing
the brake pedal from moving rearward.
CAUTION
!
Never disassemble brake pedal assembly. Disassemble will spoil its original function. If faulty
condition is found, replace it with new one.

Brakes Diagnosis Note

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, reservoir and other rubber components
(hoses). The master cylinder 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.
