164-23002 - Cleveland OEM Disc Brake

164-23002 – Cleveland Wheel & Brake Systems OEM Disc Brake

Available now on the Airparts.aero Marketplace.

The Cleveland Wheel & Brake Systems 164-23002 is a flight-critical, high-energy OEM main gear brake disc engineered for the demanding deceleration profiles of heavy aircraft. As a structural component of the main wheel assembly, this brake disc serves as the primary thermal sink and friction face for the kinetic energy absorption system during taxi, landing roll, and high-energy rejected takeoff (RTO) profiles. Operating within an external wheel interface layout, the 164-23002 is precision-manufactured to tolerate extreme localized mechanical loading and massive thermal gradients without sacrificing dimensional trueness or structural cohesion.

Produced by Cleveland Wheel & Brake Systems (a division of Parker Hannifin), this brake disc is designed to interface natively with the Cleveland 40-279A wheel assembly and matching 30-210A / 30-210C brake caliper architectures. Constructed from an advanced, fine-grained carbon steel alloy matrix, the disc undergoes precise thermal processing to maximize its surface hardness, shear strength, and thermal fatigue resistance. Its high mass footprint (weighing approximately 19.25 lbs) is carefully computed to provide the exact heat capacity matrix required to absorb and dissipate heat flux away from the inner and outer wheel halves, mitigating the risk of thermal tire deflation or localized bearing race fatigue.

The 164-23002 represents the industry benchmark in heavy utility landing gear reliability. By ensuring absolute parallelism and strict flat-plane geometric tolerances, its design optimizes contact area with metallic or organic brake linings, eliminating the threat of high-frequency brake chatter and pedal pulsation. For fleet maintenance supervisors, aerospace logistics specialists, and agricultural or cargo operators, this FAA-TSO certified brake disc guarantees absolute operational compliance and predictable wear lifecycles across grueling back-to-back flight rotations.

Why Choose 164-23002?

Installing a genuine OEM Cleveland 164-23002 brake disc ensures that the aircraft's primary stopping performance tracks perfectly with its certified landing weight parameters. Secondary aftermarket or look-alike discs often suffer from inconsistent material grain structure, leaving them prone to rapid warping, thermal coning, and surface vitrification under heavy braking loads. A deformed or structurally altered disc results in variable friction distribution, causing brake fluid cavitation, pedal fade, or complete lockup that can destroy an 11.00-12 main tire and compromise directional tracking. Cleveland's rigorous metallurgical validation protocols eliminate non-metallic inclusions, ensuring structural predictability over hundreds of high-load cycles.

The performance mechanics of the Cleveland 164-23002 center on the principles of viscoelastic frictional conversion and anisotropic thermal expansion matching. When the hydraulic piston forces the brake linings against the rotating steel surface, it initiates a high-energy kinetic energy conversion phase where operational velocities are converted directly into sensible heat. To withstand this sudden influx of high thermal flux without manifesting plastic deformation or thermal coning, the forged carbon steel substrate features an isotropic material density designed to distribute thermal load variations uniformly through the core matrix. The external lug drive configuration operates as a high-shear torque transfer interface; mechanical energy is distributed around the outer perimeter slots, directly matching the mating recesses of the split aluminum or magnesium wheel halves. This geometry minimizes stress concentrations that could induce fatigue crack propagation across the structural webs of the disc. Additionally, the precise flat-plane machining minimizes surface roughness, prompting the development of an optimized tribological transfer film between the pad linings and the steel matrix, which stabilizes the kinetic coefficient of friction and prevents localized thermal galling under heavy load profiles.

Note: The Cleveland 164-23002 is a flight-critical landing gear braking system component. Inadequate torque on wheel tie bolts, structural micro-cracks along the drive lugs, or thickness dimensions worn past the specified limits can lead to complete loss of braking action, wheel flange fragmentation, or landing gear fires. Brake disc inspection, wear limit measurement using a calibrated micrometer, and component replacement must be executed exclusively by a certified A&P/IA mechanic or authorized repair station in strict compliance with the Cleveland Component Maintenance Manual (CMM) and FAA Advisory Circular AC 43.13-1B guidelines. Always replace corresponding brake linings and inspect wheel bearing cups during every disc replacement sequence.
