Re: MovIt Carbon Silicon Carbide Rotors as PCCB Replacement?
Good stuff. I don't mean to accuse you of 'guerrilla marketing'. I just want to understand all the dynamics.
I'm not sure I totally buy the whole theory on tapered pad wear. If it were caused by a structural weakness in the caliper and it flexing, wouldn't the pads wear in a curve, less wear in the middle of the pad, more on each end where the caliper is clearly stronger because that's where the front and back are connected? I would expect tapered wear on any large surface area brake pad that is mounted in a multi piston caliper. On any brake pad, there is going to be a certain amount of torque applied to the pad during braking. What will a motorcycle do if it brakes too hard? It will flip forward because of that torque. That torque is normal. When we have a multi piston caliper, like the 6 piston units on your car, the pistons can move independently from one another, which allows the torque to turn the pad over time and wear the pad unevenly. Now the best way to compensate for this is to stagger the piston size with smaller pistons close to the leading edge and larger pistons closer to the trailing edge. I know Porsche does this on my 4 piston unit, I'm guessing they do the same on the 6 piston unit. But apparently they haven't staggered the sizes enough. If the MovIt calipers stagger the pistons differently, this may have an effect on the tapered pad wear. |

Re: MovIt Carbon Silicon Carbide Rotors as PCCB Replacement?
FWIW, an observation on pad tapering - when I use Pagid RS29s on my steel brake GT3.1, they will taper every time. I once switched to Pagid Blacks, which destroyed the stock rotors (rings of Saturn big time) but no taper wear at all. I have no idea why this should be.
