TT600 although they could just be exactly the same?

What's the distance between the bolt holes?

Yes the tt600 callipers are exactly the same unfortunately. Distance between bolt holes is 83mm I believe although the bike is in the garage at the moment so I can’t confirm that. Does 83mm sound in the right ball park?

First question...

Why?

The Speed Four and TT600 have ace brakes. Absolutely amazing. The Master cylinder ratio is well judged, the feel is good with OEM or EBC HH pads, they have loads of power.

I've never felt the brakes lacking on any of my Triumphs, and with the light weight and good forks of the Speed Four and TT600, I could outbrake people with the best of 'em. Some bikes have a bad weight distribution, or divey forks, or some kind of weird quirk that means the brakes over power the front end, but not the Speed Four.

Take the calipers off, Remove the pistons, remove the seals, clean the congealed brake fluid from the grooves in the calipers, put new seals in, replace the pistons. I think you'll find you'll end up with world class brakes again. It'll be a bit messy and a fiddly job, but well worth it.
