Braking Sensor/Switch: Adjustments
Brake Pedal and Brake Pedal Position Switch AdjustmentPedal Height on Models without Power Adjustable Pedals
1. Turn the brake pedal position switch (A) counterclockwise, and pull it back until it is no longer touching the brake pedal.
2. Pull back the carpet and find the cutout in the insulator. Lift up the insulator cutout and measure the pedal height (B) at the middle of the left side center of the pedal pad (C) to the floor.
Standard pedal height (with carpet removed): 155 mm (6 1/8 inch)
3. Loosen the pushrod locknut (A), and screw the pushrod 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 Clearance
4. Push in the brake pedal position switch until its plunger (A) is pushed in by 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 to 0.4 to 3.0 mm (0.016 to 0.118 inch) by locking the switch. Make sure the brake lights go off when the pedal is released.
5. Check the brake pedal free play.
Pedal Height on Model with Power Adjustable Pedals
1. Measure the movement range of the adjustable brake pedal by pushing the pedal position adjustment switch to fully retract the pedal, then pushing the switch to fully extend the pedal.
^ If the range of movement is not 76 mm (3 inch), check the connector that supplies power to the adjusting motor, the tightness of the nuts and bolts that secure the power adjustable pedals to the vehicle's body, the power adjustable pedals switch, and all the moving parts that relate to movement.
^ If the problem cannot be fixed, replace the power adjustable pedals assembly.
^ Check the range of movement Again. If the range is 76 mm (3 inch), go to the step 2.
2. Before checking the brake pedal height, move the brake pedal and accelerator pedal fully forward until they stop by pushing the switch.
3. Turn the brake pedal position switch (A) counterclockwise, and pull it back until it is no longer touching the brake pedal.
4. Pull back the carpet and find the cutout in the insulator. Lift up the insulator cutout and measure the pedal height (B) at the middle of the left side center of the pedal pad (C) to the floor.
Standard pedal height (with carpet removed): 155 mm (6 1/8 inch)
5. Loosen the pushrod locknut (A), and screw the pushrod 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.

6. Push in the brake pedal position switch until its plunger (A) is fully pushed in by 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 to 0.4 to 3.0 mm (0.016 to 0.118 inch) by locking the switch. Make sure the brake lights go off when the pedal is released.
7. Check the brake pedal free play.
8. Check the distance between the brake pedal and the accelerator pedal. The brake and the accelerator pedal move simultaneously with a fixed distance of 45 ± 5 mm (1.77 ± 0.2 inch).
9. Loosen the flange bolts (A) to adjust the distance between the brake pedal and the accelerator pedal. After adjustment, tighten the flange bolts firmly.
NOTE: Readjust the accelerator pedal distance from the brake pedal whenever the brake pedal is adjusted.
Pedal Free Play
1. With the engine stopped, inspect the pedal free play (A) on the pedal pad (B) by pushing the brake pedal by hand.
2. If the pedal free play is out of specification, adjust the brake pedal position switch (C). If the pedal free play is insufficient, it may result in brake drag.
