OEM 423-33-21250 is a non-friction steel plate used in the multi-disc oil-immersed brake assemblies of Komatsu WA380 series wheel loaders.
It is alternated with friction discs inside the brake pack, where it ensures precise spacing, even hydraulic pressure distribution, and thermal stability under high load conditions.
Built from hardened, wear-resistant steel, this plate is dimensionally stable under continuous heat cycles and supports optimal brake function in demanding off-road environments like mining, quarrying, and heavy-duty construction.
