We offer brake noise solutions as unique as the
factors that cause them.

Our systems-based engineering approach is a consultative process that considers how each component interacts with the entire brake system. Whether you need insulators for a new brake system or help solving noise attenuation issues in an existing one, we put every new insulator design through an exhaustive process which typically includes:

  1. Baseline Brake System Signature
  2. System Dynamic Decomposition
  3. Alternative Insulator Selection
  4. Insulator tuning
  5. Final dynamometer validation

This process takes the new brake insulator through its paces and helps us pinpoint and eliminate problems more efficiently. As a result, we can reduce the number of prototypes required which reduces your development costs and can facilitate faster post-production resolution of noise problems.
