Maintenance
PARKING BRAKE (IF EQUIPPED)
Checking the parking brake
OJF055017
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 30 kg (66 lb,
294N) 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, we recom‐
mend that the system be serviced by
an authorized Kia dealer.
Stroke : 6~7 notch
9-32
