Topic: disc brake to drum brake

[joe750]

I just picked up another 750 this weekend. Its a 1976 super sport and its a beaut.
However, the rear disc brake just doesn't appeal to me. I'm going for the cafe look with this one and i like the simplicity of the rear drum.
If I was to change the wheel to drum brake, do I need to have a different spacer in between to fill out the gap like on my hardtail or what?

I'd like to know too, I want to put a drum in the front so I can use a throttle tube set up on the left instead of a lever.

I love the way that giant drum looks on the race bikes. I'd do it!

Please keep me in the loop with spacing! I'm working on a 750 with a 350 twin front wheel. I'll definitely need to figure out the proper spacing.

Just pick up a rear wheel off ebay.   You should be able to find one for $50 bucks.    Then you can put the whole thing in your frame to see what size spacers that you'd need.   Not sure if the swing arms really change too much besides the mounting points for your calipers etc.    You might get lucky and it will bolt right up.      Then, you'll just need to weld a tab on your swingarm for the brake stay.   Or...just buy a swing arm for a 69-76 and a rear wheel for the same and you're done.

The front is pretty easy as well to change to a drum.   You'll need a rim that is drilled for a drum (spoke angles are different than the disc rim)
Just a matter of spacers to center the hub.    You'd use the caliper mounting bosses to mount the stays.

You can probably use the axle from the CB750 for the front drum - you'll just need spacers.   Shoot me a PM.   I'm putting a gigantic 4LS drum brake on the front of my latest CB750.    I had to have the brake plates machined a little as well as the axle.   Local machine shop took care of it for $50.

I have a 76 f that had comstars and rear discs when I got it. I did the same swap on mine. The rear drum uses a different stay rod than the discs. I got a 75 k swingarm with a drum wheel and just bolted it on. You can Fab up anything to work. But if you want true bolt on, you need a drum brake swingarm.
