OEM, Tier 1 and Tier 2 Testing

Vehicle manufacturers (OEMs) and major braking system suppliers (Tier 1) impose increasingly rigorous technical specifications to guarantee the performance, durability, comfort, and safety of components. These specifications go far beyond legislative standards and are often customized for platform, model, or target market.

Tier 2 suppliers (providing components such as discs, pads, shoes, calipers) must demonstrate full compliance with these specifications through dedicated tests, often performed on dynamometric test benches using proprietary procedures not replicable on standard industrial equipment.
