Second disc brake for front end

Has anyone ever converted the front brake to a dual front disc brake?!?! Had a touring model and it was EXTREMELY superior to a single, and was thinking about doing that to my 2009 heritage.

Thoughts, comments, suggestions, testimonials?!?!?

Be cautious about it. Lot of safety aspects when you start designing a front brake system.

There's a CVO package however I think that lists factory parts for it.

EDITED AGAIN: The forum member is ThunderTruck and
it appears he did not create a single "upgrade" type thread for it.
He posted most of his progress/pictures in the "What did you do to your Softail" thread...

EDIT: now if you want to "roll your own" or DIY so-to-speak.
What you can do is use the front-end components from the Touring models
since they had dual-disc frontends. You'd need the 41mm sliders, calipers,
wheel.

In either case, (aftermarket parts or HD parts), you will need a Master Cylinder.

I did indeed use the Performance Machine forks and rotors/calipers and master cylinder.
The conversion was night and day for braking. I took the more expensive bling route but you could use Harley components.

Whatever you decide on keep in mind that its not just a matter of slapping another rotor and caliper on and plumbing it up. You will also need a different master cylinder to deliver the right proportioning of fluid to the 2 calipers.

I say it’s as easy as slapping on another hub with place for the other caliper and then a divided block. You could use a larger brake reservoir from anything larger that’ll fit on the handle bar.

If money and effort look like they’re gonna be too great. You could also go to a floating rotor upfront, and a four piston caliper for probably half the money or less. It might not be as good as dual caliper, but it certainly would be better than it is.
