I suppose it depends on what you're looking for. The Brembo's are sure to be the better performing of the two, Brembo is the #1 supplier to motorcycle racers in the world. The PM's will probably look nicer/fancier while still offering an improvement over stock.

 

What year is your Dyna which is very important to answer this question. In 2006~Current Dynas, HD raised the brake tabs on the sliders to accommodate the 300mm new style rotor. A stock twin cam caliper can be used on a larger rotor than intended.

I know that the 2005 sliders do not have raised caliper mounts so the 300mm/Dresser caliper combo should work but I have never done it.

Brembo Touring 2008~Current. In order to make these calipers work on a 2000~Current baggers with 300mm rotors, HD specified longer mounting on the caliper to raise it so a 300mm rotor can be used. The slider mounting on the dressers have not been changed.

I convert over 2006~Current Dynas to dual Brembos using 300mm rotors as well as dual disk real Brembos that can be rebuilt (dresser Brembos can not) and 320mm rotors.

Fast Harley....
I have an 08 FXDC

 

I slid a Craigs List 49mm Vrod front end into my triple clamps and used a Street Glide 18" front wheel, brakes and rotors and EBC double H pads. Two finger stopping now.

 

You can not direct bolt up a set of dresser Brembo's onto a 2008 set of sliders and have the calipers work properly.

 

sweet bike . I like the way you have it set up..

The Motorcyclesuper store is where I saw the set up....

PM is American made, looks better and will stop you fast enough.
