0500118-524 – Textron Aviation OEM Right Side Brake Line Assembly
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 0500118-524 is a flight-critical, OEM flexible brake line assembly for the right-hand main landing gear on specific Cessna high-performance single-engine aircraft. This assembly is the vital conduit for transmitting high-pressure hydraulic fluid from the rigid airframe plumbing to the brake caliper on the articulating landing gear strut. It is robustly engineered to withstand the extreme dynamic environment of landing, takeoff, and ground operations, including constant flexing, vibration, and significant pressure cycling.
Constructed as a multi-layered hose, the 0500118-524 assembly incorporates a specialized inner core compatible with aviation hydraulic fluids, which is then reinforced with a braided stainless steel sheath for exceptional burst strength and abrasion resistance. The pre-formed, rigid tube sections and precision fittings at each end are designed for a perfect, leak-free interface with the master cylinder line and the brake caliper. The absolute integrity of this brake line is essential for the safe operation of the aircraft, directly influencing the pilot's ability to maintain directional control on the ground and bring the aircraft to a safe stop.

Why Choose 0500118-524?
The aircraft's braking system is a no-fail system where component quality is paramount. The OEM 0500118-524 assembly is manufactured and tested to withstand thousands of pressure cycles, extreme temperature variations, and constant vibration. Using non-certified, locally fabricated, or counterfeit 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 0500118-524 brake line's reinforcement relies on fundamental principles of material science and fluid mechanics. The braided corrosion-resistant steel (CRES) sheath provides critical hoop strength to the assembly. In accordance with Pascal's Principle, the hydraulic pressure is exerted equally in all directions within the hose. The CRES braid, possessing a high modulus of elasticity and tensile strength, resists the radial deformation (expansion) that this pressure would otherwise cause in the elastomeric inner tube. By preventing this volumetric expansion, the hose maintains a consistent internal volume, ensuring that the force applied by the pilot to the master cylinder is transmitted nearly instantaneously and without energy loss to the brake caliper. This results in a firm, responsive brake pedal feel and maximizes the efficiency of the entire braking system, a critical factor for safety during high-speed ground operations.
Note: The 0500118-524 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.
