If your parking brake is too loose or is not properly adjusted, you may encounter problems while parking, positioning and driving your car. Most of the time, car owners would send their car to a mechanic in order to fix and tighten the parking brake. However, you can actually skip this step and adjust your parking brake yourself. When your car starts to slip on a hill in its park position, you need to start tightening the parking brake.1 Remove the car's center console cover placed around your parking brake level inside your car. This is found between the seat of the driver and the front passenger.2 Use your wrench to turn its adjuster nut found at the end of your parking brake's cable rod. Loosen the adjuster nut with your wrench, while making sure that it does not come off at your parking brake cable rod's end.3 Raise your car rear wheels using your jack, and use your jack stands to support both its rear wheels.4 Pull up your parking brake handle up to two clicks or notches. Tighten your adjuster nut until you feel a slight resistance on your rear wheels whenever you spin them.5 Release your parking brake lever. Check and make sure that your rear wheels are still able to spin freely and without any resistance.6 Pull up on your parking brake lever up to three to five clicks or notches, while making sure that your car's rear wheels are not turning at all.7 Lower the car by adjusting your jack, and remove your jack stands from your car's rear wheels.

Are you saying that the car did not stop when you applied the brakes?
A vehicle does not automatically go into park when the brakes are applied. You have to manually put the vehicle in park with the shift lever.
If your car is not STOPPING when you apply the brakes - then this is a serious problem with the BRAKES!

Continually push the brake pedal to set the brakes. (With park brake off). Brakes are self adjusting and will adjust to correct position.
