I always pull my handbrake up as high as it will go when I am parked (I put the button in and yank it pretty hard, until it won't go up anymore)
It is easy to remove again.
My friend says this damages it, however I disagree with this, and hence this question! They pull it up to about 3/4 of the way
2003 Opel Agila
Am I damaging my handbrake by pulling it up all the way?
