1. Loosen stop lamp switch by rotating it counter-clockwise by
45#0#.
2. Loosen input rod lock nut (A), then rotate input rod, set pedal to
the specified height, and tighten lock nut (A).
CAUTION:
Confirm threaded end of input rod remains inside the cle-
vis.
3. Pull pedal by hand and hold it. Press stop lamp switch until its
threaded end contacts the stopper rubber.
4. While holding it against the stopper rubber, turn the switch clock-
wise by 45#O# and secure it.
CAUTION:
Be sure stopper rubber -to stop lamp switch screw
threaded end gap (C) is within specifications.
5. Check pedal free play.
CAUTION:
Be sure stop lamps go off when pedal is released.
6. Start the engine and check brake pedal depressed height.

REMOVAL
Be careful not to deform brake tube.
1. Remove the instrument of the driver-side lower panel.
2. Remove stop lamp switch from brake pedal assembly.
3. Remove snap pin and clevis pin from brake booster clevis.
4. Remove brake pedal assembly mounting nuts. Pull brake booster toward the engine compartment. Be
careful not to deform the brake tube.
5. Remove brake booster clevis from input rod.
6. Remove steering column assembly from steering member.: 16 - 21 N·m (1.6 - 2.2 kg·m, 12-15 ft·lb)

Fail-SafeEFS0019S
ABS SYSTEM
If a malfunction occurs in the electrical system, the ABS warning lamp, ESP OFF indicator lamp, and SLIP
indicator lamp in the meter will turn ON. In this condition, the ESP/TCS/ABS and EBD become one of the fol-
lowing conditions by the fail-safe function.
1. Only EBD operates. The same condition as that of models without ESP/TCS/ABS
2. ESP/TCS/ABS and EBD do not operate. Only normal brake operates on 4 wheels.
NOTE:
In the step 1 shown above, the self-diagnosis is carried out at the ignition switch is turned ON and when the
vehicle initial starts. ABS self-diagnosis noise may be heard as usual.
ESP/TCS SYSTEM
If a malfunction occurs in the electrical system, the ESP OFF indicator lamp and SLIP indicator lamp in the
meter turn on. In this condition, ESP/TCS will be deactivated and it becomes equal to that of models without
ESP/TCS. However, ABS is controlled normally.
If a malfunction occurs in the throttle control system, ESP/TCS control does not operate. Only ABS control
operates normally.
CAUTION:
If the fail-safe function operates, carry out the self-diagnosis for ESP/TCS/ABS control system.
Hydraulic CircuitEFS0019T
CAUTION:
lWhen installing, check for twist and fracture.
lMake sure that there is no interference with other parts when turning the steering clockwise or
counter clockwise.
lThe brake piping is an important safety part. If a brake fluid leak is detected, always disassemble
and replace with a new one, if necessary.
ABS FunctionsEFS0019U
1. In cases of braking suddenly or braking on slippery road (ice road), ABS functions prevent wheels from
lock, improve the stability in sudden braking, and make efficient avoidance of obstacles with steering
manipulation by detecting 4-wheel speed and controlling 4-wheel brake fluid pressure.
2. EBD is integrated in ESP/TCS/ABS system.
CAUTION:
lDuring ABS operation, the brake pedal lightly vibrates and its mechanical noise may be heard.
This is a normal condition.
