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): 211 - 214 mm
[From the surface of dash panel to the face of pedal pad]


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 approximately one quarter of a turn anticlockwise.
(3) Remove the brake pedal assembly (Refer to ).
(4) Adjust the brake pedal height by turning the clevis of brake booster.
note When the clevis is turned 180°, the pedal height is changed approximately 2 mm.
(5) Install the brake pedal assembly (Refer to ).
(6) Screw in the stop lamp switch until its thread contacts the stopper, and fix the stop lamp switch by turning it approximately one quarter of a turn clockwise.
(7) Measure the brake pedal height, and ensure that the measured value is within the standard value. When it is out of the standard value, repeat Step (3) - (6).
(8) Check that the clearance between the stop lamp switch and the stopper is as shown.
(9)
caution Check that the stop lamp does not illuminate when the brake pedal is not depressed.
Connect the connector at the stop lamp switch.
4.For vehicles with A/T, check the key interlock/shift lock mechanism (Refer to GROUP 23A, On-vehicle service - key interlock/shift lock mechanism check and adjustment).
5.Return the carpet, etc.

BRAKE PEDAL FREE PLAY



1.Turn the ignition switch to the "LOCK" (OFF) position, depress the brake pedal two or three times. After eliminating the vacuum in the brake booster, press the pedal down by hand, and confirm that the amount of movement before resistance is met (free play) is within the standard value range.
Standard value: 3 - 8 mm
2.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 500 N of force, and measure the clearance between the brake pedal and the floor board.
Standard value (C): 140 mm or more
[From the surface of floor board to the face of pedal pad]
3.If the clearance is outside the standard value, check for air trapped in the brake line, thickness of the disc brake pad, clearance between the lining and the drum and dragging in the parking brake. And then adjust and replace defective parts as required.
4.Return the carpet etc. to its original position.
