The table lists F1 cars as having "Carbon fiber brake calipers".

This is glaringly incorrect. All current brake calipers are machined from aluminum, specifically Aluminum-Lithium or Aluminum-Copper alloys. There is a rule denoting bulk elasticity modulus limit on brake calipers of 80 GPa, which was set just at that to allow the more exotic Lithium Aluminum alloys but to dis-allow Titanium alloys or anything else stiffer (There was experimentation with Titanium calipers in the past.)

Absolutely no calipers are made from composites, CF, graphite, or otherwise. Discs are Carbon-carbon.
