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.
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.
