I'm hoping someone can help me find a a source for disc brake caliper and rotor mounting/spacing standards. I am searching options to fit a disc mount on a frame and want to know the standard distances from caliper to rotor, etc.
Googling with keywords like "disc", "brake", and "iso" has been fruitless...
I have no idea, but when all else fails mount wheel, bracket to brake caliper, and position on disc using braking force to center the caliper on the disc. Be sure the caliper is in the middle of it's setting. Move wheel so bracket touches fork or frame, and tack bracket.

ISO 4210:1996 is probably what you need but any standards are extremely expensive.:(
I have not found a site where it can be read online either. Let us know if you find it.
On the Magura site:
http://www.magura.com/english/frameset/frameset.htm
On top of page menu select service -> download
Select any disc brake model from any year, hit show
and at the bottom of the list of downloads is a pdf for
the ISO 2000 disc mount standard.

Wow, Thanks a lot! I never would have found that. The diagrams help a lot although they do seem to be labeled wrong. The rearbrake diagram looks like a front fork diagram to me. The frontbrake diagram looks like the rear setup.
