(b) Adjust the pedal height.
(1) Disconnect the connector from the stop light switch.
(2) Remove the switch.
(3) Loosen the push rod clevis lock nut.
(4) Adjust the pedal height by turning the push rod.
(5) Tighten the clevis lock nut.
Torque: 26 Nm (265 kgf-cm, 19 ft-lbf)




(6) Insert the switch into the adjuster until it slightly touches the pedal.
NOTICE: Do not depress the pedal.




(7) Turn the switch a quarter turn clockwise.
Torque: 1.5 Nm (15 kgf-cm, 13 in-lbf)
NOTICE: Do not depress the pedal.
(8) Connect the connector to the switch.
(9) Check the switch clearance.
Standard stop light switch clearance:
1.5 to 2.5 mm (0.059 to 0.098 in.)





2. CHECK BRAKE PEDAL FREE PLAY
(a) Stop the engine. Depress the pedal several times until there is no vacuum in the booster. Then release the pedal.
(b) Depress the pedal until resistance is felt.
(c) Check the pedal's free play by measuring the distance between the position in the previous step and the pedal's released position.
Standard pedal free play:
1.0 to 6.0 mm (0.039 to 0.236 in.)
If the free play is not as specified, check the switch clearance in the next step.
If the free play is as specified, proceed to the "check brake pedal reserve distance" procedure.
(d) Check the switch clearance.
Standard stop light switch clearance:
1.5 to 2.5 mm (0.059 to 0.098 in.)
If the clearance is not as specified, adjust the clearance and recheck the pedal's free play.
If the clearance is as specified, troubleshoot the brake system and proceed to the "check brake pedal reserve distance" procedure.





3. CHECK BRAKE PEDAL RESERVE DISTANCE
(a) Release the parking brake lever. Start the engine.
(b) Depress the pedal and check the pedal reserve distance.
(1) Depress the pedal with a force of 490 N (50 kgf, 110 lbf).
(2) Measure the distance between the pedal and dash panel shown in the illustration.
Standard pedal reserve distance:
More than 90 mm (3.54 in.)
If the distance is not as specified, troubleshoot the brake system.
