I bought this disc pad set for my Triumph TR8 (recreation). I knew I was going to have to reshaoe the back plates wigt an angle grinder so they didn't foul on the disc hub, but once modified they fitted fine. They work fine too. Great to see they have a soft anti-squeal cushion.
There was one issue though. The split pins provided within the kit were way too short, so I had to use my old ones. My calipers are Austin Princess 4-pot, if that helps.
