    INSPECT AND ADJUST BRAKE PEDAL HEIGHT


    1. Check the brake pedal height.


      1. Turn back the carpet.

      2. Turn back the dash panel insulator assembly from the slit provided on the dash panel insulator assembly.

      3. A0003TGE03

        Measure the shortest distance between the brake pedal pad surface and floor panel.

        Table 1. Text in Illustration
        *1 Stop Light Switch Assembly
        *2 Floor Panel
        *a Brake Pedal Height
        Pedal height from floor panel
        138.5 to 148.5 mm (5.46 to 5.84 in.)

        If pedal height is not as specified, inspect and adjust the push rod length according to the procedure below.

    2. Adjust the push rod length.


      1. Remove the stop light switch assembly (Click here).

      2. Remove the brake booster with master cylinder assembly (Click here).

      3. A0006R0E04

        Loosen the lock nut and adjust the push rod length shown in the illustration by turning the brake master cylinder push rod clevis to achieve the correct length.

        Table 2. Text in Illustration
        *1 Lock Nut
        *2 Brake Master Cylinder Push Rod Clevis
        *a Push Rod Length
        Push rod length
        115.5 to 116.5 mm (4.55 to 4.58 in.)

      4. Tighten the lock nut.

        26 N*m 260 kgf*cm 19 ft.*lbf

      5. Install the brake booster with master cylinder assembly (Click here).


        • If the pedal height is incorrect even when the push rod length is adjusted, check the brake pedal support assembly and floor panel.

        • If necessary, replace the brake pedal support assembly.

      6. Install the stop light switch assembly (Click here).

    3. After adjusting the pedal height, check the brake pedal free play.

    INSPECT AND ADJUST BRAKE PEDAL STROKE SENSOR ASSEMBLY


    1. Inspect the brake pedal strike sensor assembly.


      1. Connect the GTS to the DLC3.

      2. Turn the power switch on (IG).

      3. Turn the GTS on and enter the following menus: Chassis / ABS/VSC/TRC / Data List "Stroke Sensor".

      4. Read the stroke sensor value without the brake pedal depressed.

        Standard voltage (without the brake pedal depressed)
        0.8 to 1.2 V

        If the stroke sensor value is not within the standard voltage, adjust the brake pedal stroke sensor assembly.

    2. Adjust the brake pedal stroke sensor assembly.


      1. A0003UI

        Loosen the 2 bolts.

      2. A0007RA

        Read the stroke sensor value in the Data List, and turn the brake pedal stroke sensor assembly slowly to the right or left to adjust the output voltage so that it is within the following range.

        Standard voltage (without the brake pedal depressed)
        0.8 to 1.2 V
      3. A0003UI

        Tighten the 2 bolts.

        8.5 N*m 87 kgf*cm 75 in.*lbf
        Note:

        Do not depress the brake pedal after turning the power switch on (IG).

      4. Turn the GTS off and turn the power switch off.

      5. Disconnect the GTS.

    INSPECT BRAKE PEDAL FREE PLAY


    1. A0003MPE17

      Depress the pedal until a slight resistance is felt. Measure the brake pedal free play as shown in the illustration.

      Table 3. Text in Illustration
      *a Brake Pedal Free Play
      Pedal free play
      1.0 to 6.0 mm (0.0394 to 0.236 in.)

      If the pedal free play is not as specified, check the stop light switch clearance (Click here). If the pedal free play is as specified, proceed to the Inspect Brake Pedal Reserve Distance procedure.

    INSPECT BRAKE PEDAL RESERVE DISTANCE

    Tip:

    Measure the distance at the same point used for the brake pedal height inspection.


    1. Release the parking brake.

    2. With the power switch on (READY), depress the brake pedal and measure the pedal reserve distance.

      Pedal reserve distance from the floor panel at 500 N (51 kgf, 112 lbf)
      More than 92 mm (3.62 in.)

      If the distance is not as specified, troubleshoot the brake system (Click here).
