• With any brake fully applied, a brake adjustment indicator runs out of travel or indicates that adjustment is necessary;

• Brake chamber push or pull rods move more than 80% of their max stroke or travel over centre with the brakes fully applied;

• The park brake and/or emergency brake is not capable of being fully applied without the control running out of available travel;

• The brake adjusters are bent, damaged or excessively worn, or are not properly adjusted.
