Brake check series
- The brake check series consists of three different checks:
Air brake check
- Failure to perform all three components of the air brake check correctly will result in an automatic failure of thee vehicle inspection test.
- If you realize that you have missed something or did something incorrectly during your air brake check, you may start over.
