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 1/2″ which produces 36% more pressure.

  • Outlet Ports are 1/8" NPT
  • Max Pressure is 1200 PSI
  • For use with MIL-H-5606 Fluid
