Review PIPER Master Cylinder Part

Piper PA-20 Master Cylinder (11732-02)

The Piper PA-20 Master Cylinder (Part Number: 11732-02) is an essential component of the hydraulic brake system in Piper PA-20 airplanes. This master cylinder is responsible for converting the mechanical force of the pilot's brake pedal input into hydraulic pressure that ultimately acts upon the wheels to slow down or stop the aircraft.

Crafted from high-strength materials, this master cylinder ensures reliable and consistent performance under various operating conditions. It features a robust, single-piston design with a bore diameter of approximately 0.75 inches and a stroke length of around 0.75 inches. The cylinder body is constructed from forged steel, providing excellent durability and resistance to fatigue.

The piston, in turn, is made of heat-treated steel to ensure minimal expansion and contraction during temperature changes, maintaining a tight seal with the cylinder body. The seal itself is made of a high-quality, pressure-resistant rubber material that ensures a leak-free operation.

Equipped with an integrated reservoir, this master cylinder ensures an adequate supply of hydraulic fluid to the system. The reservoir is transparent, enabling easy inspection of the fluid level and its condition. The fluid, typically a mineral oil or a synthetic aviation hydraulic fluid, is vital for lubricating the cylinder components and preventing corrosion.

The 11732-02 master cylinder is designed to meet or exceed the stringent requirements of FAA-PMA (Federal Aviation Administration-Production Approval Maintenance) standards. This ensures that the master cylinder not only provides optimal performance but also complies with the highest safety and quality standards.

In summary, the Piper PA-20 Master Cylinder (Part Number: 11732-02) is a critical component of the aircraft's hydraulic brake system. Its robust design, use of high-quality materials, and adherence to FAA-PMA standards make it a reliable and long-lasting solution for maintaining the safety and functionality of your Piper PA-20 aircraft.
