Check whether the stroke is within specification when the parking brake pedal is depressed with 20 kgf (44 lb, 196N) of force. Also, the parking brake alone should securely hold the vehicle on a fairly steep grade. If the stroke is more or less than specified, have the system serviced by a professional workshop. Kia recommends to visit an authorised Kia dealer/service partner.
Stroke: 4~5 notch
