Somewhere in the Hacks section there is a thread on leading links. Maybe someone can find it and post a link?

I just moved my calipers to a fixed mount behind shocks from floating in front and the lifting stopped.

Back when I was building shocks (about 35 years ago), I had a customer who liked to hillclimb, but hated to come down. He had leading links put on his bike to make it rise when he but the front brakes on. No floaters here.

I built a leading link front end for my 4130 sheet metal framed bike in 1969. I made a parallel linkage because I wanted it to be like a conventional set of forks.

Now the whole message is that you can design the front end to lift or dive when you put the brakes on. With an equal sided parrallelogram for the linkage you get a neutral no rise or dive bike.

If you move the linkage from parallel to closer to the swing arm pivot, the bike rises with brakes. In the limit the linkage goes to the pivot and makes a fixed caliper setup.

If you move the linkage from parallel up from the pivot, the bike dives with brakes.

Suit yourself.
