Steve - I'm still investigating possible replacements from other model Pug/Cit. The slave cylinder looks like it can be replaced from another model but the master is not looking promising.
Rolebama - Yup you are correct about them being fitted to all 2.1td 406's. I think it will be possible to repair it if it's a split pipe, in fact I know it works, I would like to incorporate a bleed point in the line between master and slave.
I managed to damage the master so would like to replace that without paying silly money
