164-20900 – Cleveland Wheels and Brakes Wheel Brake Disc

Available now on the Airparts.aero Marketplace.

Overview

The Cleveland 164-20900 is a genuine Original Equipment Manufacturer (OEM) brake disc, a flight-critical component at the heart of the braking system for a specific range of high-performance and turboprop aircraft. This disc, or rotor, is engineered by Cleveland Wheels & Brakes (a division of Parker Hannifin) to provide a durable, high-friction surface for the brake linings to act upon. Manufactured from a specialized steel alloy and precision-ground to exacting tolerances, the 164-20900 is designed to repeatedly absorb and dissipate the immense thermal energy generated during landing and braking, ensuring safe and reliable stopping power.

Key Features

• High-Strength Steel Alloy: Fabricated from a proprietary steel alloy, heat-treated to provide exceptional thermal mass, resistance to warping, and high-temperature durability. This ensures the disc maintains its structural integrity under the immense heat and pressure of maximum braking effort.
• Precision Ground Surface: The disc surfaces are precision-ground to be perfectly flat and parallel. This provides a smooth, uniform friction surface for the brake linings, which prevents vibration, eliminates brake chatter, and ensures even wear of the linings.
• Engineered Thermal Management: Designed to absorb and then efficiently dissipate massive amounts of heat. Its specific mass and surface area are engineered to manage the thermal loads generated when converting the aircraft's kinetic energy into heat, reducing the risk of brake fade.
• Wear Indicator: As a primary wear component, the disc's thickness is the key indicator of its service life. It is manufactured to a specific new thickness and has a clearly defined minimum wear thickness, providing a clear, measurable criterion for replacement.
  
• Genuine Cleveland OEM Part: As the genuine OEM part, it guarantees the correct material composition, heat treatment, and dimensional tolerances specified for the corresponding Cleveland brake assemblies, ensuring certified performance and safety.

Applications

The 164-20900 is the central rotating component of the disc brake system:

• Braking Force Generation: Provides the friction surface that the brake linings press against to generate the torque required to slow the rotation of the wheel.
• Kinetic Energy Conversion: Its primary function during braking is to act as a heat sink, converting the aircraft's immense kinetic energy into thermal energy.
• Mandatory Maintenance Item: A critical wear item that must be inspected for thickness, warping, heat checking, and cracks at regular service intervals and replaced when it reaches its minimum service limits.

Why Choose 164-20900?

The safety of every landing depends on the reliability and performance of the braking system, especially in a faster, heavier turboprop aircraft. The Cleveland 164-20900 brake disc is an engineered solution, not just a piece of steel. Its specific alloy and heat treatment are designed to prevent catastrophic failure under the extreme thermal stresses of braking. Using a genuine Cleveland OEM part is the only way to ensure you are installing a disc with the certified material properties and quality control required to stop your aircraft safely, every time. For a flight-critical component, there is no substitute for genuine, traceable OEM parts.

The 164-20900 brake disc functions as a thermal energy sink. During a landing, the kinetic energy (

) of the aircraft must be converted into heat (

) to bring it to a stop. This conversion happens at the interface between the stationary brake linings and the rotating 164-20900 disc. The disc's material must be able to absorb this massive influx of thermal energy without warping or developing micro-cracks (heat checking). Its thickness is directly related to its "heat sink" capacity. As the disc wears and becomes thinner from normal use, its ability to absorb and dissipate heat is reduced. This is why adhering to the minimum wear thickness of 0.272 inches is a critical airworthiness requirement to prevent brake fade or failure.

Note: This is a flight-critical component. Installation must be performed by a certified A&P or AME mechanic in accordance with the aircraft and component maintenance manuals. Brake discs should always be inspected for condition and thickness at every tire change and brake lining replacement. It is highly recommended to replace discs in pairs on the same axle to ensure even braking performance.
