6 Pot Brake Calipers Means...

 

6 Pot calipers means that the brake calipers are holding 6 pistons. Different types of calipers (the thing that holds the pistons themselves) will hold different amounts and types of pistons. The calipers themselves are made from a variety of materials, steel and aluminum being the most popular - steel for durability, and aluminum for weight. The more pistons the better the braking power and pedal feel.
