BRAKE PEDAL CHECK AND ADJUSTMENT


caution Do not apply grease or lubricant to the switch and the switch installation section to avoid malfunction of the switch. In addition, do not use gloves which have grease on them.

BRAKE PEDAL HEIGHT

1.Check that shown distance "A" meets the standard value.
Standard value (A): 208.6 - 214.6 mm
(From the surface of retainer to the face of pedal pad)


2.When the brake pedal height is not within the standard value, adjust the brake pedal in the following procedure.
(1) Disconnect the stop lamp switch connector.
(2) Loosen the stop lamp switch by turning it anti-clockwise by approximately 1/8 turn.
(3) Loosen the lock nut of operating rod, then turn the serrated section of operating rod using the pliers to adjust the brake pedal height to the standard value.
Tightening torque: 26 ± 4 N·m
note After adjust the brake pedal height, tighten the lock nut of operating rod with holding the serrated section of operating rod by using the pliers.
(4) Press in the stop lamp switch until the thread section of stop lamp switch comes in contact with the pedal stopper. Then, secure the stop lamp switch by turning it clockwise by approximately 1/8 turn. While doing this, pull and hold the brake pedal by hand.
(5) Check that the clearance between the stop lamp switch and the pedal stopper is as shown in the figure.
Standard value (B): 0.5 - 1.5 mm
(6)
caution Make sure that the stop lamp is not illuminated when the brake pedal is not depressed.
Connect the stop lamp switch connector.

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 (C): 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 RETAINER
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 "D" shown in the figure.
3.Start the engine, depress the brake pedal with approximately 500 N of force, and measure the distance "E" between the silencer and brake pedal shown in the figure.
4.Check that the total value of "D" and "E" measured in the previous items 2 and 3 is within the standard value.
Standard value (D + E):
70 mm or more <4G6>, 65 mm or more <4N1>, 80 mm or more <6B3>
(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.
