Casting process and product

A braking system comprising:

• a brake component, wherein the brake component is made from an ADC12 aluminum alloy and wherein the ADC12 aluminum alloy is cast into the brake component according to a high pressure, slow velocity casting technique;
• wherein the ADC12 alloy consists essentially of:
• 9.6 to 12.0 percent silicon;
• 0.0 to 1.3 percent iron;
• 0.0 to 0.5 percent manganese;
• 0.0 to 0.3 percent magnesium;
• 0.0 to 1.0 percent zinc;
• 0.0 to 0.5 percent nickel;
• 0.0 to 0.3 percent tin;
• 1.5 to 3.5 percent copper;
• 0.0 to 0.15 percent one or more other elements;
• and aluminum as the remainder;
• 9.6 to 12.0 percent silicon;
