Many thanks - mine's a pre 2006 car so has a slightly different arrangement, but looking in the parts book the general principle seems to be holding 2 firmly, unscrew 1 - I'll give it a try. I'm slightly suspicious though as on my handbrake it looks like 1 is secured by a long thin, steel spring pin. But as the handbrake was ineffective anyway, I guess if I break it, I'm not really any worse off...
