Crystalyte Disk Brake

Got to work with the file..
I tried a variety of dremel bits, but the steel used on these disks is quite hard.. the best solution was a round file ( Used to sharpen Chainsaw tips !! ) .. i have a bunch of them from all sizes.. started with the smaller one and worked my way up until i made the marker marks.. disapear.
Keep lubricating the file with WD-40 or cutting oil if you have some handy.

Then i had to file down the inside of the disk ( red marks ) with a flat file so that it would fit on the adapter but inside the threads.. otherwise it would not spin onto the motor cover far enough..
Also had to trip the aluminum adapter ( yellow marks ) as it has a lip that prevents the disk from seating flush on the adapter.

And voila !
on an X5302 !
Required a shim on the threaded collar behind the adapter.. similar to what is used behind a freewheel so that it does not seat against the hub body..

I'll be curious about that rim and tire combination. I'm running 24" rims and 3" tires and figure that if I could switch to wider rims that the tire would work better. My current rims are designed for a 1.75 tire. (too narrow)
Is that a 24" rim? 20"?

omg Ypedal... you used a FILE to do that? Dude, that disk is high grade stainless steel for crying out loud. 
Amazing!
Thanks for the very detailed explanation. That may work for me but with the 11'' motorcycle disk only, we’ll see. For other folks though THAT is a great solution. Too bad that the threaded adapter is not standard for the mounting holes.
Nice to see the Stingray again!!

Yep.. that sucker was a job to file out.. but thick gloves.. and a few beers it got done ! 8)
In this picture you can see the clearance with the shim in place.. about half inch. I see no reason why yours would not fit the same way.. Is you caliper unusually large between the hub and disk ?
The chopper will take time to finish, all funds are currently tied up in my inventory " hopefully on it's way soon !! " .. once i sell a few bits i'll be finishing up the chop !... can't wait.. will be a fun ride !

As you can see, my setup is different from anybody’s. I had to use these flat bars on each sides to hold the hub because the axle was too short for the swing arm.
So the bolts heads seen on the second picture reduce the clearance even more. My disk will have to be closer to the hub, there for a bigger disk is necessary to allow the caliper to go outside the hub, giving it more room.
I’m still surprised that one half of your caliper would fit there with only 5/8''. Your caliper must be different than mine. I measured ¾'' total distance for half my caliper.

Yup, 11'' rotor it's gonna be, but that is not all...
the disk being larger than a standard 8'', we will have to make a bracket from the 2 holes on the swing arm, to the caliper.

Short axles suck... I ordered every single motor ( both 4 and 5 series ) with 9 inch = 230mm long... plenty of axle to mount disk brakes.. and torque arms on both sides with inches to spare.. even with a 7 speed on there !! 
I just hope and pray Kenny got it right.. time will tell. :lol:
For a large diameter disk brake to work, you have to pick your frame carefully.. some swingarms have the tubes tapered in towards the pivot point.. i got lucky with the 05 Chaos as the tubes are litterally paralell with the tire leaving plenty of room.
The chopper will get done this summer.. for sure.. it drives me nuts to walk past it every day ( In my kitchen mind you ! lol ) it's begging to be finished !...
Me Needs mo money !!!......

hi stevo - best to stick to the mechanical disk brakes.
because of the issues i had with stretching dropouts etc. i opted for a frame with a rear rim brake.
if i get a front hub motor though, this will cause a lot more problems.

Best bet would be to drop into a bike shop and check the calipers available..
You can add shims to the back of the thread-on adapter to push the disk further away from the hub to an extent, ( same spacers used on the freewheel side ) but then you need forks wide enough to allow the hub to shift to the right of the bike.

Heres a picture of a Hayes So1e hydraulic disc brake. It has just the one caliper on the outside. The inside has a disk pad and adjustment screw.
Its the thinnest one I could find.
At 1 inch or 25mm it wont fit in your space.

How large a freewheel are you using on the other side ? single or multi-speed?
The entire hub would need to shift to the right to allow the proper spacing.

Steveo,
Can you post a picture of the sprocket side with ruler to show how much space we have to play with.

Sprocket side of 5304 hub motor ...
i'm also putting better pivot point bearings in the frame
