BRAKE PEDAL CHECK AND ADJUSTMENT



BRAKE PEDAL HEIGHT


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

2.Pierce a needle or similar material to the silencer and melting sheets, and measure the thickness of "A" shown in the figure.
3.Measure the distance between the silencer and brake pedal "B" shown in the figure.
4.Check that the total value of "A" and "B" measured in the previous items 2 and 3 is within the standard value.
Standard value (A + B): 178.3 - 181.3 mm
[From the surface of dash panel to the face of pedal pad]


5.If the brake pedal height is not within the standard value, follow the procedure below.
(1) Disconnect the stop lamp switch connector, loosen the lock nut, and move the stop lamp switch to a position where it dose not contact the brake pedal arm.
(2) Adjust the brake pedal height by turning the operating rod with pliers (with the operating rod lock nut loosen).
(3) Screw in the stop lamp switch until its thread contacts the stopper, and fix the stop lamp switch by turning it approximately one eighth of a turn clockwise.
(4) Check that the clearance between the stop lamp switch and the stopper is as shown.
(5)
caution Check that the stop lamp does not illuminate when the brake pedal is not depressed.
Connect the connector at the stop lamp switch.
6.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 DASH PANEL


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

2.Pierce a needle or similar material to the silencer and melting sheets, and measure the thickness of "A" shown in the figure.
3.Start the engine, depress the brake pedal with approximately 490 N of force, and measure the distance "B" between the silencer and brake pedal shown in the figure.
4.Check that the total value of "A" and "B" measured in the previous items 2 and 3 is within the standard value.
Standard value (A + B): 75 mm or more
[From the surface of dash panel to the face of pedal pad]
5.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.
6.Return the carpet etc. to its original position.
