You really should not have bothered! The cable/hydraulic set up on the Seca is not very good. I fitted a pair of callipers off of an R1, along with the hydraulic brake leaver from a breakers yard. I had new brake lines. I had to get an aluminium converter plate to bolt the callipers to the fork legs. Made a pattern out of three ply, then got it cut out of thick aluminium plate. The whole lot cost about £100.00, but I now have fantastic brakes.
