Which term describes a gradient that is temporary and occurs during transients when the brake system is not fully charged?

• A. False gradient
• B. Normal gradient
• C. Inverse gradient
• D. Steady gradient

Answer: (A)

Transient behavior in a brake system occurs while it’s not yet fully charged, and during this moment the measured gradient is not representative of the steady state. This temporary difference is called a false gradient because it arises from the evolving pressure distribution as the lines fill and pressure waves settle; it will disappear once the system is fully charged and the transients fade. In contrast, a normal gradient is the steady-state pressure difference you expect during normal operation, an inverse gradient would mean the gradient is in the opposite direction, and a steady gradient refers to a constant gradient under stable conditions. So the term fits because the gradient is temporary and tied to the incomplete charging process.
