      *a Pedal Height
      *1 Clevis Lock Nut
      *2 Stop Light Switch Assembly

      Check the brake pedal height.

      Standard Pedal Height from Dash Panel
      Item Specified Condition
      for LHD 157.2 to 167.2 mm (6.19 to 6.58 in.)
      for RHD 160.2 to 170.2 mm (6.31 to 6.71 in.)

    2. Adjust the brake pedal height.


      1. Disconnect the stop light switch connector.

      2. Remove the stop light switch assembly.

      3. Loosen the push rod clevis lock nut.

      4. Adjust the brake pedal height by turning the push rod.

      5. Tighten the push rod clevis lock nut.

        Torque:
        26 N*m  { 265 kgf*cm, 19 ft.*lbf }

      6. Insert the stop light switch into the adjuster mounting until the switch body touches the brake pedal.

        Note

        Do not depress the brake pedal.

      7. Turn the switch a quarter turn clockwise.

        Torque:
        1.5 N*m  { 15 kgf*cm, 13 in.*lbf }
        or less

        Note

        Do not depress the pedal.

      8. Connect the connector to the switch.

      9. Check the switch clearance.

        Stop light switch clearance
        1.5 to 2.6 mm (0.0591 to 0.0984 in.)

  2. CHECK BRAKE PEDAL FREE PLAY

      *a Pedal Free Play

      Stop the engine. Depress the brake pedal several times until no vacuum is left in the brake booster. Release the brake pedal.

    2. Depress the pedal until a slight resistance is felt. Measure the distance as shown in the illustration.

      If the pedal free play is not as specified, check the stop light switch clearance.

      Pedal free play
      1.0 to 6.0 mm (0.0394 to 0.236 in.)

      Tech Tips

      Check the brake pedal free play at the same location as that used when checking the brake pedal height.

  3. CHECK BRAKE PEDAL RESERVE DISTANCE

    Tech Tips

    Measure the distance from the same point as that used for the brake pedal height inspection.


    1. Release the parking brake.

    2. With the engine running, depress the brake pedal and measure the pedal reserve distance.

      Standard Pedal Reserve Distance from the asphalt sheet at 490 N (50 kgf, 110.2 lbf)
      Item Specified Condition
      for LHD (Manual Transmission) More than 102 mm (4.02 in.)
      for LHD (Automatic Transmission) More than 105 mm (4.13 in.)
      for RHD More than 108 mm (4.25 in.)

      If the distance is not as specified, troubleshoot the brake system.

      Tech Tips

      Insert a ruler into the slit to measure the pedal reserve distance.
