Disc and Drum Brake Dynamometer Squeal Noise Matrix
- Ground Vehicle Standard
This procedure is applicable to high frequency squeal type noise occurrences for passenger car and light truck type vehicles that are used under conventional operating conditions. The procedure does not encompass the consequences associated with changes in environment related to temperature and humidity variations.
This recommended test practice is intended to establish a common universally recognized method for performing a series of screening test sequences that identify the propensity of a brake assembly to generate squeal noise under a variety of test conditions.
