The objectives for this (non-binding) VDA recommendation by the German Association of the Automotive Industry are as follows:
To define the technical standards for the operational strength testing of passenger car brake calipers of vehicle categories M1, M1G and N1. To provide a summary of necessary operating strength tests for the development release of brake calipers.
This recommendation covers all requirements with regard to operating strength, which must be met by a passenger car caliper on public roads, even under high loading. It does not apply to special operating conditions such as motorsport events. In these cases, special tests may be needed with more severe or different requirements.
Alternative test methods may be used and have to be coordinated among development partners. The correlation must be demonstrated.
