   3. Loosen the clevis lock nut.
   4. Adjust the pedal height by turning the pedal push rod.
   5. Tighten the push rod lock nut.

      Torque: 26 N.m (265 kgf.cm, 19 ft.lbf) 

   6. Install the stop lamp switch.
   7. Connect the connector to the stop lamp switch.
   8. Push the brake pedal in 5-15 mm (0.20-0.59 in.), and turn the stop lamp switch to lock the nut in the position where the stop lamp goes off.

1. Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster.
2. Push in the pedal until the beginning of the resistance is felt.

   Measure the distance, as shown in the installation.
