What must be done daily with an air brake equipped unit?

Draining air tanks daily is essential for maintaining the proper function of an air brake system. Over time, moisture and contaminants can accumulate in the air tanks, leading to issues such as corrosion, reduced braking effectiveness, and increased wear on brake system components. By regularly draining the air tanks, technicians can ensure that only dry, clean air is maintained in the system, which helps to prevent these problems and contributes to the overall safety and reliability of the vehicle.

While adjusting brakes, pressure testing the compressor, and rotating slack adjusters are important maintenance tasks, they are not necessarily required on a daily basis. Routine checks and adjustments can be performed as part of a scheduled maintenance plan rather than through daily inspections. In contrast, draining the air tanks is a quick and crucial step that should be repeated each day to protect the air brake system from moisture-related issues.
