brake rotor question
I have been having some rear brake pedal being hard to engage lately, in an earlier post, and after putting new fluid in both front and back, with no relief for the inital problem I guess i will let the dealer Digi Tech it. They said they would charge me the shop minimum of .5 hrs.
So anyway while I was doing the fluid, I put my dial indicator on the front rotors and they were slightly beyond the manual stated max runout of .008, R side at .010 and L side at .012. So now I am looking at new rotors ( they do have the vibration associated with the runout) and am wondering why the wide range of prices. Is it just because they can or is there a real reason like material or machining process. Not looking at floaters, just replacing the standard front pair.

Rotors come in 1 piece and two piece. Cog drive, floaters, bolted together solid stainless, carbon composite, etc. Generally speaking, on a newer bagger like you have a 2 piece cog drive or floating rotor will work the best as a 2 piece rotor cools much qiker than a 1 piece polsied rotor.
The brembo calipers create an excessive amount of heat which is what causes the rotors to warp. On a 1 piece rotor the heat needs to dissipate through the entire rotor before cooling. On a 2 piece rotor the heat only needs to dissipate to the edge of the outer band.
On my bagger I will be getting Lyndall carbon composites as I find them to have the best stopping power and the lifetime warranty is unbeatable.
