Yup. Bought it new in July of '95. Still have it. Four inch spring lift. Four inch shackle lift. 35 x 12.50 x 15 BFG Mud Terrains. I have an LT1 motor, an NV4500 tranny and an Atlas transfer case sitting in my parent's barn back home that was supposed to go into the Jeep. Was going to turn the truck into a rock crawler but when I moved down here, there isn't much use for an eight cylinder in the Jeep.

You may even try these Brembo side mounts that I have on my 2005 Dyna. I have put these on many baggers with our 320 mm SS Floating rotors (3 1/4 Lbs).as well as our MMC (2.2 Lbs.) and adapters which works very well and there is not much of a comparison with the older 11 1/2" rotors/systems. Again, great brake pad material is very important increasing your friction coefficient. You need to think in terms as a complete all around package. Think also about tires.
Another option is the XR1200 caliper which has the exact same internals as the Honda Fireblade. They also share the same brake pads so you can purchase inexpensive great brake material pads all over the world. The mounts are the same as the old style twin cam so they are direct bolt up. If you have some size laced wheels such as a 19" which the bulky caliper will hit the spokes. You can also purchase adapters and use 320mm rotors.
Yes, you can bolt them up to a Bagger or a twin cam Dyna and they cost only $185 at HD.

just found your site a few days back & what you guys are doing with the Carbon Fiber wheels, Inverted Forks, Brembo Mounts, Hollow Axles, & MMC Rotors, is OFF THE ***'IN HOOK !!!!
i turned a buddy on to your site as he's building a 120" FXR & i hope he uses ALL your products

I have the 6 piston PM on my 08 FB and love it. IMHO it out performs the stock caliper (not a brembo on the FB). Not a huge difference but definitely noticeable. I think the pads that come installed in the PM are average at best, also I think you need to upgrade your stock master cylinder from a 9/16 to 5/8 to get maximum performance.

A brake caliper is a simple hydraulic device. If you are going from a 4 piston HD caliper to a PM 4 piston caliper there will be no difference if the pistons are the same size...it is simple math...the caliper does not know what name is written on the side of it....to paraphrase Smokey. Pads can make a big difference...but remember pads that stop a lot quicker, eat rotors a lot quicker...something to think about if you are running expensive rotors. No brake will save your azz if you are not paying attention.

I think that's the main point. PM caliper may be bolt-on replacement for HD stock -- but with stock master cylinder and stock lines and stock rotor, just how is the claimed improvement achieved?

I just bought a Jaybrake J-Six Ultra Front Brake Caliper. At the end of this month I'm going on a nine day - 4,000 mile trip. When I return I plan to install it... will let you know how it works..
