Maximum Stroke of Brake Pedal ▶
Check the brake pedal with below procedures: -
Start the engine.
Pump the brake pedal around 3 times.
Depress the brake pedal with approx. 30 kg
and measure the distance (A) between the
upper surface of pedal pad and the lower
dash panel.
If the measured value is out of the specified
value, adjust the length. 1.

Check the pedal height with below procedures: -
Start the engine and measure the length (A)
between floor mat and pedal.
If the measured value is out of the specified
value, adjust the length. 1.
2.
Adjust the pedal height with below procedures: -
Disconnect the stop lamp switch connector.
Unscrew the lock nut and remove the stop
lamp switch assembly.
Loosen the lock nut on the pedal push rod.
Turn the pedal push rod to adjust the pedal
height.
Tighten the lock nut.
Install the stop lamp switch assembly.
Connect the stop lamp switch connector.
Check if the stop lamps come on when
pressing the brake pedal around 5 mm.
If the stop lamp dpes not come on, adjust the
stop lamp switch assembly again.
If the stop lamps come on, tighten the lock nut
and measure the pedal height again. 1.

Specified value (A)3 ~ 10mm
Connect the multimeter to stop lamp switch
connector and check if the continuity exists
when pushing in the plunger. If the continuity
doesn't exist, the stop lamp switch is normal. - Pedal Free Play ▶
Stop Lamp Switch ▶Check the pedal free play with below
procedures: -
Stop the engine.
Depress the brake pedal several times to
discharge the vacuum pressure of the brake
booster.
Depress the brake pedal until you feel the
resistance, and measure the movement (A). 1.
2.
3.
Below the specified value: Check if the
distance between the outer case of stop lamp
switch and the brake pedal.
Over the specified value: It may be caused by
bigger clearance between the clevis pin and
the brake pedal arm. Replace the
components if necessary. -

Let the engine run for 1 to 2 minutes and
stop it. If the brake pedal stroke is shortened
as pumping the brake pedal, the system is
normal. If not, the system is defective.
Depress the brake pedal several times with
engine off. If the brake goes down when
starting engine with pedal depressed, the
system is normal. If not, the system is
defective.
Depress the brake pedal when the engine is
running. If the pedal height is not changed for
30 seconds after stopping the engine, the
system is normal. If not, the system is
defective. 1.

If the above three checks are OK, the system is
normal. If any condition is not met, check the
valve, vacuum hose and brake booster. Brake Booster ▶

Brake Fluid ▶
Brake Fluid Type ▶ 1. Color
Ligh gold (New oil) → Brown → Black -
2. Service Interval/Type
Change: every 2 years, Type: DOT4
The water in the brake fluid has an adverse effect to the brake system. If the fluid contains
around 3% of water, the boiling point of the brake fluid goes down by 25%. It will cause the vapor
lock frequently.
Water content in fluid: around 3% after 18 months, around 7~10% after few years
The water ib fluid makes the corrosion in the brake lines, deforms and deteriorates the rubber
components, brake calipers and pistons. -
DOT4: Brake fluid for premium vehicle. Lower water absorbing rate AND higher boiling point than
DOT3
Brake Fluid Level Check ▶
The brake fluid level should be between "MAX"
and "MIN" on the reservoir. If it is below "MIN"
mark, check for oil leaks and refill the reservoir
with the specified fluid.

Pad Thickness 1.
Measure the pad thickness and replace it if
it is below the wear limit. -

Disc Thickness 2.
Measure the disc thickness at over four
points.
If any of measured points is below the wea

New disc Wear limit
28 mm 25.4 mm
Disc Run-Out 3.
Install the dial gauge on the side of brake
disc and measure the run-out while rotating
the brake disc.
If the measured value exceeds the limit,
replace the brake disc with new one.
Otherwise, it may cause the pedal vibration
and shimmy when braking. -
