On certain trucks, the cotter pin that retains the brake pedal clevis pin may not have been installed. The clevis pin connects the brake pedal to the brake foot valve; therefore, if the pin were to come loose, the driver would not be able to apply the service brakes. This could cause a vehicle crash with injury or death. Correction: Dealers will inspect and, if missing, install a cotter pin in the brake pedal clevis pin.
