From tomk1960:
"A good friend of mine who was a Honda dealer in TX for many years has been watching my progress with my 78 GL.
Today he asked me why I was sticking with the stock single piston calipers. He suggested bolting on some dual piston calipers like the ones used on many of the early-to-mid 80's Hondas.
I didn't think it was possible, since bolt patterns, geometries, etc. may vary. I wasn't sure that there was a caliper hanger that could bolt right on.
Well, I'm really happy that I listened to him. When I got home, I grabbed a spare right caliper and hanger from my stock of "F" parts.
Guess what - it bolts right on and everything appears to line up perfectly!"
I plan to do it real soon.
A little extra work is required for the 75-77 setup but not that much from what I've read.

With the Comstars it's a simple bolt on.
I'll ask about bikes with spokes.
Re: GL 1000 front brake upgrade info
Any word on spoke wheels modification/ possiblity?
I have a Gl1000k3 and bought spoke wheels and I'm having brake issues: are the discs a different spacing? Are there other brackets is have to get? Or would the described modification work too?

Re: GL 1000 front brake upgrade info
The 78 setup is different from the 75-77.
Re: GL 1000 front brake upgrade info
Thanks..
. Could I get 75-77 brackets? Would that work? Or is that not enough and should I switch the whole brake calipers from a 75-77? Or possibly....look for 75-77 rotors?
