BRAKE PEDAL(for RHD) ADJUSTMENT

PROCEDURE


  1. INSPECT AND ADJUST BRAKE PEDAL


    1. Inspect the brake pedal type (for 1NZ-FE).


      1. Remove the brake pedal pad.

        Measure the dimension A as shown in the illustration to determine the brake pedal type.

        Dimension A
        Brake Pedal Type Dimension A
        for 1NZ-FE Type A 11.9 mm (0.469 in.)
        for 1NZ-FE Type B 18 mm (0.709 in.)

      3. Install the brake pedal pad.

    2. Inspect the brake pedal height.


      1. Remove the front door scuff plate RH. Click here

      2. Remove the cowl side trim board RH. Click here

      3. Remove the No. 2 dash panel insulator pad.

      4. Turn back carpet.

      5. Inspect brake pedal height.

        Pedal height from floor panel
        Brake Pedal Type Pedal Height
        except 1NZ-FE

        113.5 to 123.5 mm

        (4.47 to 4.86 in.)
        for 1NZ-FE Type A

        107.3 to 117.3 mm

        (4.22 to 4.62 in.)
        for 1NZ-FE Type B

        111.9 to 121.9 mm

        (4.41 to 4.80 in.)

        If the pedal height is incorrect, adjust it.

        Tech Tips

        Measure the pedal height between the floor base surface and the pedal as shown in the illustration.

        107.3 to 117.3 mm

        (4.22 to 4.62 in.)
        for 1NZ-FE Type B

        111.9 to 121.9 mm

        (4.41 to 4.80 in.)

      5. Tighten the push rod lock nut.

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

        Note

        Do not depress the brake pedal.

        Tech Tips

        The turning torque for installing the stop light switch:

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

      8. Check the stop light switch clearance.

        Stop light switch clearance
        0.5 to 2.6 mm (0.020 to 0.102 in.)

      9. Connect the connector to the stop light switch.

      *a Pedal Free Play

      Inspect the brake pedal free play.


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

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

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

        If incorrect, troubleshoot the brake system.

    5. Inspect the brake pedal reserve distance.

      Tech Tips

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


      1. Remove the front door scuff plate RH. Click here

      2. Remove the cowl side trim board RH. Click here

      3. Remove the No. 2 dash panel insulator pad.

      4. Turn back carpet.

        *a Reserve Distance

        Release the parking brake lever. With the engine running, depress the pedal and measure the pedal reserve distance as shown.

        Pedal reserve distance from floor at 300 N (31 kgf, 67.4 lbf)
        Brake Pedal Type Pedal Reserve Distance
        except 1NZ-FE More than 79 mm (3.11 in.)
        for 1NZ-FE Type A More than 78 mm (3.07 in.)
        for 1NZ-FE Type B More than 80 mm (3.15 in.)

        Tech Tips

        Sound and resistance from the brake booster when the brake pedal is depressed without a vacuum does not indicate a problem.

        If incorrect, troubleshoot the brake system.
