Application Note: Detecting Debris Under Brake Caliper Seal

End-of-line leak tests were not catching some brake caliper defects. Process anomalies such as small debris pieces, or “chips” in the seal groove were resulting in very subtle defects which were impossible to detect. Caliper defects were being discovered by vehicle assembly plants or by customers, which led to expensive warranty repairs and productivity disruptions. The manufacturer required a solution with minimal tooling and fixturing modification that would reliably improve caliper quality without affecting yield.
