I'm converting from single disk to dual with mags on my 2014 FXDB and I got a great deal on some take-off Brembos from a touring bike. I've been doing research and have seen some conflicting evidence that this works on late-model Dynas.

Has anyone successfully done the single to dual on the 06-Up dyna with the Brembo takeoffs with success? Additional note, if necessary, I'd like to run Galfer rotors.

Thanks.

 

 

HD Touring brembos are not radial mounted like sport bikes. I mounted them on my old XL and it worked, but I think the 06-17 Dyna lower forks cause the touring calipers to sit on the outer diameter of the rotor. Someone else can confirm this.

 

 

 

 

Had time to kill waiting on florence to arrive, I found the attached photo in an older thread posted by Howard. It looks like the brakes will work until the pads wear. Once they are grooved to the thickness of the rotor you will no longer have front brakes...

 

Look at the brake pads hanging over the rotor. I went into detail why you or anyone should not use this as well as as why this happens. Lower caliper mounts will work with the OEM HD Dresser Brembo calipers. Look at your original rotor and look at the outside perimeter, why does anyone ever not use the outside of the brake rotor for pad wear? " It looks like the brakes will work until the pads wear" I am sure it will work up until the time the rotor comes apart and shatters. You are good until than. If anyone has ever witnessed a rotor come part, I am sure if you survive you may not wish to do it again. Kind of like the lowering blocks and the stressing of the angle on the swing arm when the swing arm comes apart, been doing so for many years. The vendors say that these are much better quality. Has to do with the design and the angle of stress. In both cases, it is up to you as it is your bike as well as the welfare of your passenger. Keep one's own counsel.

 

Only found a picture, not the full explanation. Also I think a little bit of my sarcasm was lost in translation, wouldn't suggest using brakes that way.

 

Sorry, the sarcasm went over my head. I have wrote many posts on this subject when I first starting converting over 2006 FXD's to twin rotors and members did this abortion over a carefully laid out "How To", step by step. At that time I was testing and developing CMC rotors with Cycle World on the track when a rotor came apart. Luckily no one was hurt and the set up was correct. The problem was the manufacturing process of squeeze casting (two molds pressed together under high pressure) V/S spin casting (Varying the speed of the rotations) when the material was poured onto the spinning mould, in a molten state than air cooled to eliminate air pockets and the sand (silicone) moves to the outer circumference of the rotor.

Running a brake pad on the un-swept rotor edge could cause fractures. Add the speed (RPM's), centrifugal force, and vibration the brake pads exert may ruin your day. Think first than stay safe. You may get away with it until you do not.
