What should happen to the ABS in the event of a trailer supply line failure?

In the event of a trailer supply line failure, the Anti-lock Braking System (ABS) will stop working. The ABS relies on a constant supply of air to function properly, as it controls the brake pressure to prevent wheel lockup during hard braking. When the trailer supply line fails, it disrupts the air supply necessary for the ABS to operate, leading to its inactivation.

This scenario highlights the importance of maintaining the integrity of the air supply lines, as any disruption can directly impact the safety features of the braking system. Without the functioning ABS, the trailer will still have the basic air braking system operational, but the enhanced safety feature provided by the ABS will be lost, making it crucial for drivers to remain vigilant and responsive to braking situations.
