0500118-506 – Textron Aviation OEM Left Side Brake Line Assembly
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 0500118-506 is a flight-critical, OEM flexible brake line assembly engineered for the left-hand main landing gear on specific models of the Cessna 210 Centurion series. This component is the essential hydraulic conduit that transmits high-pressure fluid from the rigid airframe plumbing to the brake caliper on the articulating landing gear strut. It is meticulously designed to withstand the extreme dynamic stresses of ground operations, including constant flexing during gear travel, high-frequency vibration, and the significant pressure fluctuations of the braking system.
Constructed as a multi-layered hose, the 0500118-506 assembly features a specialized inner core compatible with aviation hydraulic fluids, which is reinforced with a braided corrosion-resistant steel (CRES) sheath. This construction provides exceptional burst strength and protects against abrasion and chafing. The assembly is completed with factory-installed, precision fittings and pre-bent rigid tube sections to ensure a perfect, leak-free installation. The integrity of this brake line is paramount to the safe operation of the aircraft on the ground.

Why Choose 0500118-506?
An aircraft's braking system is a no-fail system where component quality cannot be compromised. The OEM 0500118-506 assembly is manufactured and tested to withstand thousands of pressure cycles, extreme temperature variations, and constant vibration. Using non-certified, locally fabricated brake lines introduces a severe risk of hose rupture or fitting failure. Such a failure can lead to a complete loss of braking on one side, resulting in a ground loop, runway excursion, or other catastrophic ground incident. Sourcing this genuine Textron Aviation part ensures compliance, safety, and the peace of mind that comes from using a component built to the aircraft's original design specifications.
The engineering design of the 0500118-506 brake line is a study in material science and fluid dynamics. The choice of a braided stainless steel (CRES) sheath over the elastomeric inner core is critical. This braid acts as a hydrostatic reinforcement, preventing the hose from expanding radially under pressure. According to Pascal's Principle, the pressure exerted by the hydraulic fluid is transmitted equally throughout the system; any volumetric expansion of the hose would dissipate this energy, resulting in a "spongy" brake feel and reduced braking force at the caliper. The CRES braid, with its high tensile strength and modulus of elasticity, constrains this expansion, ensuring that nearly all of the force applied at the master cylinder is converted into clamping force at the brake disc. Furthermore, the braid's interwoven construction provides exceptional resistance to torsional stress and external abrasion, a vital characteristic for a component located in the harsh, debris-rich environment of the landing gear assembly.
Note: The 0500118-506 is a flight-critical safety component. Installation must be performed by a certified A&P mechanic in strict accordance with the current Textron Aviation maintenance manual for the specific aircraft model. All fittings must be torqued to the specified values, and the system must be properly bled of air and leak-checked prior to return to service. Brake hoses are condition and/or life-limited items and must be inspected and replaced as required by the maintenance schedule.
