BRAKE PEDAL RETREAT SUPPRESSION MECHANISM
The brake pedal retreat suppression mechanism that
restraints the retraction of the brake pedal pad sur-
face during a frontal collision has been adopted in
order to reduce the shock to the driver's feet.
When the brake booster is crushed rearward by the
engine retreat during a frontal collision, the installa-
tion surface of the brake pedal is retreated. In this
case, the end of the pedal support is forcibly slid
down and back by the interference with the slope
mounted on the front deck crossmember assembly.
At the same time, the linkage comprised of the pedal
support, pedal arm, and push rod moves the brake
pedal pad surface forward.
