With everything being equal (piston size, pad size, rotor...etc....)
Would there be a performance difference between the two setups besides the obvious weight difference? I'm thinking at normal temps, both would be equal. I'm also guessing that once one gets more aggressive with the brakes, the aluminum calipers would be better and would be less susceptible to brake fade due to the better heat dissipation of the aluminum. |

Heat is transferred from the pads to the fluid through the pistons. Good place for stainless is there.
QUOTE Iron has 3x the stiffness of aluminum, so theoretically 1/3 of the section could be used with equal stiffness (and equal weight) with iron Actually 1/3 the section would result in 1/27 the stiffness if you keep the material the same. If you use Iron, you can get away with a thickness of about 70% of the thickness you would need in aluminum for the same stiffness. Andrew |
