Two Lucas branded Sierra front brake hoses on eBay for £9.95 and free delivery. Not as trendy as the braided type but the price is right for cost conscious Locostbuilders. More than ten sets available:

mate are you missing something? we take sierra's apart not rebuild them lol

good find though

Wish i found them a few months ago before i brought mine!

Any idea what length they are please?

Dunno but you could guesstimate it based on the threaded ends being 10mm across!
