What is a driver required to do when the loading of the braking system’s air tanks takes longer than a reasonable time?
- Correct answer: Drive to a garage to repair the malfunction.
- Reduce the engine’s RPM, to make the work of the compressor more efficient.
- Check the system’s fuel filter and, if required, clean it.
- Wait until the tanks are filled up, and ignore the problem.
Why this is the answer
The correct answer in the official bank: Drive to a garage to repair the malfunction.
When the air tanks take too long to fill, something is wrong in the air system, such as a leak or a weak compressor, and it must not be ignored. The truck should go to a garage for repair, only once the pressure has reached the normal level and while driving slowly and carefully. Lowering engine RPM actually slows the compressor, and the fuel filter has nothing to do with the air brakes.
