BRAKE SWITCH CLEARANCE
Screw in the brake switch until its plunger is fully depressed (threded end (A) touching the pad (B) on the pedal arm)
then brake off the switch 3/4 turn to make 0.5 ~ 1.0 mm(0.0197 ~ 0.0394 in.) of clearance between the brake switch
connector. Make sure that the brake lights go off when the pedal is released.
PEDAL FREE PLAY
1.With the engine off, inspect the pedal free play (A) on the pedal pad (B) by pushing the pedal by hand.
Free play: 3 ~ 8 mm (0.12 ~ 0.31 in.)
2.If the pedal free play is out of specification, adjust the brake switch (C). If the pedal free play is insufficient, it may
result in brake drag.
INSPECTION OF FRONT DISC BRAKE PAD
1.Check the brake pad thickness through the caliper body inspection hole.
Pad thickness
Standard value : 10.5 mm ( 0.41 in)
Service limit : 2 mm (0.0787 in)

DESCRIPTION
The EBD system (Electronic Brake force Distribution) as a sub- system of the ABS system is to control the effective
adhesion utilization by the rear wheels.
It further utilizes the efficiency of highly developed ABS equipment by controlling the slip of the rear wheels in the
partial braking range.
The brake force is moved even closer to the optimum and controlled electronically, thus dispensing with the need for
the proportioning valve.
The proportioning valve, because of a mechanical device, has limitations to achieve an ideal brake force distribution
tothe rear wheels as well as to carry out the flexible brake force distribution proportioning to the vehicle load or weight
increasing. And in the event of malfunctioning, driver cannot notice whether it fails or not.
EBD controlled by the ABS Control Module, calculates the slip ratio of each wheel at all times and controls the brake
pressure of the rear wheels not to exceed that of the front wheels.
If the EBD fails, the EBD warning lamp (Parking brake lamp) lights up.
ADVANTAGES
a.Function improvement of the base - brake system.
b. Compensation for the different friction coefficients.
c. Elimination of the proportioning valve.
d. Failure recognition by the warning lamp.
