I have decided not to refurb too. I found a pair of new calipers for £70 and am looking for a pair of braided hoses next.
I thought might just as well take this approach than buy 2nd hand callipers, and stick with the existing rubber hoses even though the hoses look in good condition.
Debating if I would paint the new callipers a colour or leave as is. The hoses I'm looking for will be blue so maybe I could paint them a blue colour.
