easy
its easy, there a quite a few threads on this topic, but apart from using a hoover or a magnet which are stupid if you ask me ! just get a new cable poke it through the hole ! and use a small thin paper clip bent in to a really small flat hook on the end it will take a little time but shouldnt take more than 5 mins maybe 10 at the most for each cable.
p.s i could do with a length of clear sleeving for the rear brake on my rascal ! also pmed you .
cheers
