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

      7. Install the stop lamp switch assy.
      8. Connect the connector to the stop lamp switch assy.
      9. Push the brake pedal in 5 to 10 mm (0.20 to 0.39 in.) and turn the stop lamp switch assy to lock the nut in the position where the stop lamp goes off.
      10. After installation, push the brake pedal in 5 to 10 mm (0.20 to 0.39 in.), and check that stop lamp comes on.
      11. Tighten the stop lamp switch lock nut.

        Torque:  17 N.m (173 kgf.cm, 13 ft.lbf)

  2. CHECK PEDAL FREE PLAY 
    1. Stop the engine and depress the brake pedal several times until no vacuum remains in the booster.
    2. Press the pedal until resistance is felt. Measure the distance, as shown inFig 2 .

      Pedal free play:  1 to 6 mm (0.04 to 0.24 in.)

      If incorrect, proceed to the following step.

      1. Check the stop lamp switch clearance.

        Stop lamp switch clearance:  0.5 to 2.4 mm (0.020 to 0.095 in.)
