I've replaced the rear brake pipes on mine and I'd say it was much, much easier than doing the same job on a Rover 45. They thoughtfully provided joints on the 260, in both pipes, just below the centre console. Makes replacing the rear pipes which are (in my opinion) the ones which corrode, a doddle. The one on the offside cannot follow exactly the same route as the original unless you remove the fuel tank, because there is an infuriatingly-inaccessible clip up there above the tank, but I've got mine close enough and secure. I put new hoses on at the same time.
