Brakes; been away twice for a week at a time this year, leaving the car parked up. Both times I found the brakes either stuck on the handbrake - not freeing off the drums, having to rev a bit and drive off to free them, and the discs sounded hissy as if scraping away for a while. It looks like the drums & discs need virtually everyday use in these beasts. Maybe the steel in the discs is more susceptible to rust than other cars as even a 2 day park up can cause the hissing noise from the brakes.
