Thank you for your reply it will not be being repaired as its now ben damaged beyond repair the handbrake failed parked up on a hill, very upset so being scrapped
Ouch! Sorry to hear that.
It has never happened to me, but I still take the precautions driving school taught me, so it's become sorta second nature:
1) When parking on an incline, always park with the wheels facing towards the curb (downhill) or away from the curb (uphill).
2) Put the car in 1st gear (or P if automatic), and let it rest on the gear/parking pawl before you apply the parking brake.
One advantage to precaution #2 is that there's less wear on the parking brake,
and the gearboxes on modern cars are built on purpose to handle this parking method.
On cars from the 70's or older, I was advised to apply the handbrake before putting the car in gear.
Not sure what the driving schools in UK teach about this bit, but you might find something useful here to prevent this from happening to your next car.
