INTRUSION-MINIMIZING BRAKE PEDAL FUNCTION
• An intrusion-minimizing brake pedal, which minimizes the amount of rearward pedal thrust in a frontal collision,
has been adopted. Due to this, impact force to the lower body of the driver is softened.

INTRUSION-MINIMIZING BRAKE PEDAL OPERATION
• In a frontal collision, the brake pedal is forced rearward by the movement of the engine and other parts.
• Brackets A and B break away from bracket C, which is fixed to the body.
• Bracket B is freed allowing it and the pedal arm to rotate together at pivot fulcrum D of bracket A, thereby
preventing the rearward movement of the brake pedal.
