- Remove the driver's dashboard undercover (see DRIVER'S DASHBOARD UNDERCOVER REMOVAL/INSTALLATION ).
- Turn the brake pedal position switch (A) counterclockwise, and pull it back until it is no longer touching the brake pedal.
- Disconnect idle stop switch connector (B).
- Turn the idle stop switch counterclockwise, and pull it back until it is no longer touching the brake pedal.
- Pull back the carpet and find the cutout (C) in the insulation. Measure the pedal height (D) at the center side of the pedal pad (E) to the floor without the insulation.
Standard pedal height (with carpet moved): 147 mm (5.79 in)
- Loosen the push rod locknut (A), and screw the pushrod (B) in or out with pliers until the standard pedal height from the floor is reached. After adjustment, tighten the locknut firmly. Do not adjust the pedal height with the pushrod pressed.
- Brake pedal position switch adjustment: Lift up on the brake pedal by hand. Push in the brake pedal position switch until its plunger is fully pressed (threaded end (A) touching the pad (B) on the pedal arm). Then, turn the switch 45 ° clockwise to lock it. The gap between the brake pedal position switch and the pad is automatically adjusted 0.7 mm (0.03 in) by locking the switch. Make sure the brake lights go off when the pedal is released.
- Idle stop switch adjustment: Adjust the idle stop switch (C). Screw in the idle stop switch until its plunger is fully pressed (threaded end (D) is touching the pad on the pedal arm). Then back off the switch 1/2-3/4 turn to make 0.6-0.9 mm (0.02-0.04 in) of clearance between the threaded end and the pad. Tighten the locknut firmly. Connect the idle stop switch connector. When finished, start the engine, and warm it up to normal operating temperature (the radiator fan comes on), then make sure the engine stops when the brake pedal is pressed.NOTE:
- When either the brake pedal position switch or the idle stop switch needs adjusting, both switches must be adjusted together to keep their functions synchronized. Always adjust the brake pedal position switch first, then adjust the idle stop switch; never adjust the switches independently.
- 'When the brake pedal is released, the brake pedal position switch is normally open and the idle stop switch is normally closed.
- Install the all removed parts in the reverse order of removal.
- Check the brake pedal free play.
