Recently fitted the EBC Contour rotors and EBC HH pads to the front of my Standard. Entire braking system now completely overhauled as I did both master cylinders at the same time, put HH pads on the OE rear; Pistons and seals in all calipers replaced a while back and also all lines with braided steel.

Here's one of the old ones . Nothing wrong with it, in fact very good nick .

When I picked the bike up from the workshop there was good initial bite but overall performance was a tad worse than stock.( Just new pads of course...)
Just done 140 miles and, Wow! A real difference. Much more feel and control - you know through the lever exactly what's happening. Lever is firmer and grab is immediate. No fade at all and very predictable in terms of stopping. Not earth shattering performance increase - still takes a fair amount of pressure - but IMO that's not necessarily a bad thing. Hopefully things should get better as they bed in further.
My guess it about two yards less stopping distance from 20mph, perhaps several times that at 40.
An expensive fix, but a good one. I'm glad I did it. I can certainly recommend these rotors.
Thanks to everyone for the advice.
