With use the hand brake can become “loose” and will need pulling higher than normal to stop the car from rolling. You can adjust the hand brake yourself from inside the car. It is a simple job and should take no more than 15 minutes.
If you are not sure of what you are doing please leave this job to a qualified mechanic. I am NOT responsible if you get it wrong!
First you will need access to the adjustment mechanism which is under the centre console. Remove the two screws that secure the rear part of the centre console, there is one on each side, then pull the centre console upwards and it should come away.
Once the centre console is out of the way you should be able to see the handbrake adjustment mechanism.
Now to take up the slack in the handbrake tighten the nut shown in the picture below. Test the handbrake a few times, make sure that the rear wheels rotate freely when it is off. Also make sure the hand brake will stop the car from rolling when it is on.
