Home › CDL Practice Tests › Air Brakes Questions › Question 140
What condition of a brake hose connection at a glad hand or fitting is a defect?
- A.A loose connection or a worn, missing, or leaking seal that lets air escape
- B.A seal that sits evenly and keeps the coupling airtight
- C.A coupling that locks firmly to its mating half
- D.A hose supported so it does not drag or chafe
Correct answer
A. A loose connection or a worn, missing, or leaking seal that lets air escape
Why
Glad hand seals and fittings have to hold full system pressure every time the brakes work. A leaking coupling wastes compressor capacity and can drop trailer braking or supply pressure when it is needed most.
