Brake interlock systems are used on petroleum tank trailers to automatically apply the brakes during loading and unloading, preventing accidental movement. The bracket provides a stable attachment point for the interlock valve hardware, and it is replaced if the original bracket becomes damaged, corroded, or missing to ensure the safety system remains operational.
