If a 2-2.5 (between two and two-and-a-half) ton saloon car:
- is manual
- between 7-15 years old
- parked on an incline of around 20-30 degrees
- for roughly 8 hours a day
- 5 days a week
What can the expected damage/wear (if any) on the handbrake be?
Assume that the handbrake is handled normally and not "yanked" up each time.
