Will the radial caliper be attached to the SR400 fork?
I tried cutting the outer tube of the right fork to confirm that.

The result is an ordinary fork.

What I’m thinking to install is Brembo’s 20.8343.21.
The price of it is about 22000 yen.

The inside is made in this way.

I sharpen the whole part where at the bottom axle shaft is sticking out and what I integrated with caliper ‘s support.
Next, cut the screws to the outside of the outer tube.
And, if I paint the LOCTITE and screw it in, it is OK.

After that, I tried taking upper oil seals and metal.
However, it was rusted and sticking and could not be removed at all.

I used the time in unexpected places.
