BRAKE PEDAL CHECK AND ADJUSTMENT



BRAKE PEDAL HEIGHT


1.Turn up the carpet, etc. under the brake pedal.

2.Measure the brake pedal height as illustrated.
Standard value (A):

    192 - 195 mm <LHD>
    187 - 190 mm <RHD>


3.If the brake pedal height is not within the standard value, follow the procedure below.
(1) Disconnect the stop lamp switch connector.
(2) Loosen the stop lamp switch by turning it approx. 1/4 turns anticlockwise.
(3) Remove the brake pedal and pedal support member (Refer to ).
(4) Adjust the brake pedal height by turning the clevis.
(5) Install the brake pedal and pedal support member (Refer to ).
(6) Push the stop lamp switch until its thread touches the stopper. Then secure the switch by turning it clockwise approximately 1/4 turns. During this work, pull the brake pedal towards you to hold.
(7) Connect the connector at the stop lamp switch.
note Check that the stop lamp does not illuminate when the brake pedal is not depressed.
4.Return the carpet, etc.

BRAKE PEDAL FREE PLAY


1.Turn the ignition switch ON, and fully accumulate the brake fluid in the HBB accumulator.
note If the brake fluid is not fully accumulated in the accumulator, the pump motor will start to run. When the accumulator is fully accumulated, the pump motor stops. When the brake fluid is accumulated in the accumulator, the pump motor does not run.

2.Operate the pedal by hand, and check that the pedal stroke (free play) meets the standard value at the point where resistance is felt.
Standard value (B): 3 mm or less
3.If the brake pedal play is not within the standard value, check the following, and adjust or replace if necessary:

  • Excessive play between the brake pedal and the clevis pin, or between the clevis pin and the brake booster operating rod

  • Brake pedal height

  • Installation position of the stop lamp switch, etc.

CLEARANCE BETWEEN BRAKE PEDAL AND FLOOR BOARD


1.Turn up the carpet etc. under the brake pedal.

2.Start the engine, depress the brake pedal with approximately 490 N of force, and measure the clearance between the brake pedal and the floorboard.
Standard value (C):

    85 mm or more <Short wheelbase>
    80 mm or more <Long wheelbase>
3.If the clearance is outside the standard value, check for air trapped in the brake line and thickness of the disc brake pad.
4.Return the carpet, etc.
