you are correct, the 4 strokes were always a year behind
85 they were still twin shock

So a floating disk won't flutter and knock the piston back in a fixed caliper ?
Is that what you are saying ?

It does a little, takes a extra pull to get firm. The other reason why i changed them.
Its normal for a piston to retrack a little, thats what the square sealing O rings do on the piston to reduce drag.
They early set up rattles and moves around alot, the caliper with slides dont move easy so never get lose in the pads.

the above is true..i mainly dislike the single piston brembo because it lacks stopping power...its weaker than a properly set up dls drum.

Justin is dead nuts on point with the 85/86 ft brembo disc set up. DLS smokes it in stopping power. 87 twin piston way better also.

I'd been pretty sick with bronchitis, but I did get the rear shock serviced. Buddy who used to wrench for the old Dirt Works Husqvarna-KTM shop that was once in North Jackson, OH took care of it.

Found the radiators are bent, and many of the rubber mounts are shot. Missing the front brake pad pin too and I'm having a heck of a time sourcing one.

I'll try to get some progress pics up soon. Appreciate the input and suggestions thus far.
