380 series aluminum which sheds heat five times faster than traditional cast iron|
calipers, actually pulling heat away from the rotors.
New Bi-metal piston combines a stainless steel outer piston with an aluminum
inner sleeve to shed braking heat fast. The stainless steel outer piston greatly
enhances piston withdrawal after braking.
Oversize rubber boot is 50% thicker by design and provides a more positive and
faster piston withdrawal.
This feature, along with the special coating actually reduces brake heating even
after repeated stops.
