Thanks for those replies. The problem is I need a different size on the back than the front so whatever I use will not match, though I can get close. The frame would have been built for 27 inch wheel but the forks are for 700c. The drop on the front is about 45~50mm but on the back is about 60mm. That said, I am tempted to use two brakes anyway because I bought the levers and the cable clips and I think it would look nice. I've never ridden a fixie myself; I'm only doing up it because it's a nice frame and its going to waste. I'll probably sell it when it's done so I wondered what more knowledgeable people than me thought. I had some Weinman brakes that were more knackered than I realised, I bought some dual-pivot brakes not realising they'd have recessed bolts, then I bought some Shimano 600's - very nice bujt the back one is 2 or 3 mm's short. I don't know if it makes sense to drill out the difference? Maybe it would weaken them?
