Made of a special air craft grade aluminum that is not affected by the high heat like many of the materials used by other companies. Most rotor buttons are load bearing, it is crucial that you get this right.

Free floating brake buttons will allow you to convert semi floating rotors into full floating rotors. Free floating rotors reduce the drag from the pads which in turn reduces the heat build up in the rotors and the heat transfer to the fluid which often causes brake fade. The buttons will also eliminate stuck buttons which also cause brake pulsing at the lever. These free floating buttons will allow the bike to roll easier with less drag from the pads/rotor blade and reduce the unsprung rotating weight by over .5 pound per rotor on most rotors.

Tech Information

What is Full-Floating? Full floating rotors were originally designed to reduce the tendency towards thermal stress induced distortion due to uneven thermal expansion under load. Prior to the introduction (by Brembo) of this design, brake rotors in the motorcycle industry were simply round discs bolted solidly to the wheel. You may remember if you've been around long enough, the rotors on the early CB750 and Z-1's were nearly 7mm thick and weighed accordingly. This was in effort to keep them from warping. Now days, the only road bikes coming through with solid mount (front) brakes are the Cruisers and budget bikes.

Today's Sportbikes brake rotors work remarkably well considering their mass-produced (stamped) manufacturing process. These are technically semi-floaters as the outer SS blade is nearly bolted solid to the carrier via the stamped stainless steel rivets.

True full-floaters move on the carriers, this allows them to self-center in the caliper for reduced brake drag and "float" unimpeded for unrestricted expansion and contraction during repeated thermal cycling. The only serious down side is a bit of rattle that reminds you these are indeed full-floaters.

Does all this guarantee they won't distort under severe duty conditions? No, unfortunately, there's precious few guarantee's these days. But they do perform as advertised in improving overall braking performance while significantly reducing distortion tendency.

The buttons were super easy to install. One thing to note is if you have the 4.5mm rotor, make sure to use one of the additional washers on each button.

Awesome product!
