My '07 Street Bob (FXDB) has an upgraded front floating rotor (44364-00). I am in the market for brake pads and want to know if this is a stainless steel rotor, so I can determine pad type (sintered, organic, etc). I Googled the part number and searched on several HD dealer websites with no luck in determining its composition.

Can anybody tell me if this is a stainless rotor?

 

Modern bike rotors are nearly all stainless steel. Older Glides had an iron rear (out of sight behind the bags) and some rotors can be had in carbon fibre now. You're safe going with stainless! Most cars have iron rotors, which is a better material, but it doesn't look as good when in full view on a bike!

 

Thanks for the info. I am looking for brake pads, not rotors, and the catalogs/internet searches said to make sure sintered brake pads are used with stainless rotors.

Because of the importance of brakes I just want to confirm....does this mean that my rotor (which is not carbon fiber) will work with sintered pads?

 

Yes. There are other options. If you go to the Dyna forum and use 'search this forum' and enter 'sintered', you'll be able to see what pads other Dyna owners are using. On a brief look it includes sintered pads especially EBC.

 

The friction ring on that rotor is stainless steel. Most 2 piece rotors have a carrier (center portion) made out of aluminum and the friction ring made out of stainless steel. There is only 1 other rotor I know of with a friction ring made of an alternate material which si the Lyndall composite rotors that utilize MMC (metal matrix composite) for the friction rings.

As far as what pads to run, most pads will work good. We prefer the Lyndall Z plus pads as they last a long time and put out much less dust while still providing excellent stopping power.
