      *1	Stop Light Switch Assembly
      *2	Dash Panel
      *a	Brake Pedal Height

      Standard pedal height from dash panel

      179.9 to 189.9 mm (7.08 to 7.48 in.)

      NOTE:

      Do not adjust the brake pedal height. Doing so by changing the push rod length will structurally change the pedal ratio.

      If the pedal height is incorrect, check that there is no damage in the brake pedal support assembly and dash panel.

      Even if there is damage, there is no problem if the reserve distance is within the standard value. If necessary, replace these parts.

HINT: 

If the pedal height is incorrect, check and adjust the stop light switch clearance.

1. Disconnect the stop light switch connector.
2. Turn the stop light switch assembly counterclockwise and remove it.
3. Insert the stop light switch assembly until the body hits the cushion.

   *1	Stop Light Switch Assembly
   *a	1.5 to 2.5 mm

   NOTE:

   When inserting the stop light switch assembly, support the pedal from behind so that the pedal is not pushed in.

4. Make a quarter turn clockwise to install the stop light switch assembly.

   HINT: 

   Due to the inverse screw structure, if the stop light switch assembly is turned clockwise, the stop light switch assembly moves in the direction to be pulled out.

   NOTE:

   The turning torque for installing the stop light switch assembly should be 1.5 N.m (15 kgf/cm, 13 in.*lbf) or less.

5. Connect the stop light switch connector.
6. Check the protrusion of the rod.

   Standard protrusion of the rod

   1.5 to 2.5 mm (0.0591 to 0.0984 in.)

1. Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster.

   *a	Brake Pedal Free Play

2. Push in the brake pedal until the beginning of the resistance is felt. Measure the distance as shown in the illustration.

   Standard pedal free play

   1.0 to 6.0 mm (0.0394 to 0.236 in.)

1. Release the parking brake pedal.
2. With the engine running, depress the brake pedal and measure the pedal reserve distance as shown in the illustration.

   *a	Pedal Reserve Distance

   Standard pedal reserve distance from asphalt sheet at 490 N (50 kgf, 110.2 lbf)

   More than 104 mm (4.09 in.)

   If incorrect, troubleshoot the brake system (Refer to PROBLEM SYMPTOMS TABLE [08/2015 - ] ).
