Our standard master cylinder has a piston bore of 5/8" and is recommended for most aircraft. For aircraft with oversized tires, poor brake pedal geometry, etc. you may wish to use a master cylinder with a piston diameter of 9/16" which produces 19% more brake fluid pressure, or one with 1/2" piston diameter which produces 36% more fluid pressure.

Displacement of master cylinders with a piston bore of 5/8" is 0.441 cu-in.
Displacement of master cylinders with a piston bore of 9/16" is 0.357 cu-in.
Displacement of master cylinders with a piston bore of 1/2" is 0.282 cu-in.
