What is Caliper piston area? How do measure it?
It is the total surface area of all the pistons in one half of the caliper. The piston area can be determine using the formula, Area = pi x the piston radius squared x the number of pistons. For an example, lets use a six piston caliper and for ease of the math, lets say that all the pistons are equal in diameter at 1.5 inches: 3.14 x .5625 x 3 = 5.29 square inches.
