Just a quick tip from an idiot! Don't be in too much of a rush to get everything bolted up. I started from the caliper and worked my way upwards, complete renewal. The really fiddly bit was fixing the hoses to the brake light switch, finally finishing at the master cylinder. It was then that I realised that the bend in the hose fixing was to locate it correctly at the master cylinder end, and not t'other way round as I had managed to, nice and securely as well!
