BRAKE PEDAL

Purpose/Function

• An intrusion-minimizing brake pedal has been adopted to the brake pedal to provide for a measure of safety in the event of an accident.

• The intrusion-minimizing brake pedal mechanism reduces impact to the lower extremities of the driver by minimizing the amount of rearward brake pedal thrust in a frontal collision.

Construction/Operation

During normal braking

• When the brake pedal is depressed, the pedal arm rotates at the pin A fulcrum point, and the pedal depression force is transmitted to the fork of the power brake unit.

• This pedal depression force pushes in the fork to operate the brakes.

Intrusion-minimizing brake pedal

• In a frontal collision, the brake pedal is forced rearward by the movement of the engine and other parts.

• The pedal arm section of the rearward moving pedal contacts the bracket.

• The pedal arm section and bracket contact point of the brake pedal rotates around the fulcrum point softening impact to the lower body of the driver.
