Buderus Guss

What Buderus Guss does

Breyden (formerly Buderus Guss) is a German automotive component manufacturer specializing in high-quality cast and precision-machined brake and drive parts. Its core product portfolio includes classic and carbide-coated (Hartmetallbeschichtung) brake discs, brake calipers, lightweight brake disc variants with self-manufactured aluminum pots (Aluminiumtöpfen), and precision-cast drive components such as ready-to-install differential gears. The company is the pioneer of the first-generation iDisc, an emissions-reducing brake disc technology, and is currently developing a Euro 7-compliant next generation, positioning itself as an innovation leader in emissions-reduced brake systems.

Underlying capabilities center on traditional metallurgy and manufacturing: deep expertise in casting (Giessen) and machining of cast parts, a proprietary hard metal coating process for brake discs, and ready-to-install (einbaufertig) serial production. The company operates five German production sites following the December 2025 integration of four former MAT (Maschinen- und Antriebstechnik) locations in Neunkirchen, Immenhausen, Altenburg, and Ueckermünde, expanding its footprint from a single site to a multi-site industrial platform.

The business model is B2B hardware sales through direct enterprise relationships with major European automotive OEMs and Tier-1 suppliers. Named OEM customers include SEAT, Mercedes-Benz, BMW, and Škoda, with additional worldwide Tier-1 supply. Revenue is generated through long-term development and serial production supply contracts, with pricing negotiated individually and not publicly disclosed. Breyden is privately held and has been a portfolio company of AEQUITA, a Munich-based industrial group, since May 2024, when AEQUITA completed its acquisition of the legacy Buderus Guss business ahead of the October 2024 rebranding to Breyden.
