HavocTurbo,

Does EBC make a model to fit a K2?

I'll check.... what year? Or am I being completely stupid?

No but it looks like Steveone has come up with a pretty decent solution.

It's a few replies before...

Well, a couple weeks of breaking in the new EBC Rotors, and the phantom squeal is BACK!!! What the #$%*?!!!!
It's gotta be this blasted caliper of mine. Anyone know if a 77 cb70K front caliper will fit on a K4? It seems to be, it is a little bit better design, and might not have the squeal tendency that the old K Tokicos have?

Stevie,
Is your caliper properly set up, with a lubricated caliper pivot?
Make sure the steel line isn't pushing the caliper out of whack either.
Watching that stuff, I've never had the dreaded brake squeal...

Thanks Pete, I haven't checked those things in a bit. I'll let you know. You've got the K caliper though right? So, that could be why you don't have the dreaded brake squeal?

I've got both the new and old style 750 calipers...my 350's and 550's don't squeal either...I guess I'm just lucky...

ok i just read a lot and my head hurts.

I must be greatly oversimplifying this, but can't you just take a performance caliper from a modern bike with spoked wheels (sport classic or bonneville), make a relocator, and bolt it up? or is the stock rotor too thick, new caliper too wide?

dual piston dirt bike calipers are made to work with fixed rotors and spoked wheels?

in a nutshell: no you cant, main issue will be clearance between inner side of the thicker caliper and spokes. There are ways around it, it has been done but not a straight bolt on, the new adaptor cant really solve that.

dirt bike calipers (the ones that are thin, with two moving pistons) have indeed sliding pins mounted calipers, so you'll have to rengineer that too.

last, all modern calipers are designed to work on a much narrower disc/ swept area. not a deal breaker but some how engineering-ly wrong in my book.

head spinning again?  ;)

Right on TG. Yeah, the stock CB rotors are thicker than most (if not all) newer rotors. And clearance between the spokes and rotor is definitely an issue. Goldwing front end would solve a lot of that. I'll probably switch over one of these days and go for a dual set up.

Yes Honda 750 K calipers up to 78 are thicker than anything made the last 20 years.. if you have a 2pce double acting caliper you may be able to shim moddle but it may hit spokes.

The Honda caliper mounts are vastly dissimilar to modern stuff..

 Good news though, the big Duc rotors are the right bolt pattern for our wheels..& Ysamaha mags too...
