Final answer:

Dragging air brakes can be caused by a stuck air governor piston, a leaking park control valve, reversed gladhands, or a sticking plunger in the foot valve. Among these, a sticking plunger is the most significant cause. Proper diagnosis and repair are crucial for safe braking performance.


Explanation:

Possible Causes for Dragging Air Brakes

If the air brakes on the front steer axle of a tractor are dragging after a brake application, there are several potential causes to consider:

  • A stuck air governor piston: If the air governor piston is stuck, it may not regulate air pressure effectively, leading to improper brake function.
  • A leaking park control valve: If the park control valve is leaking, it can prevent the brakes from releasing completely, causing dragging.
  • Reversed gladhands on the trailer: Incorrectly connected gladhands may result in improper air supply or pressure, affecting brake performance.
  • A sticking plunger in the foot valve: A sticking plunger can also hinder the release of air pressure, which can lead to dragging brakes.

Among these options, the most common cause of dragging air brakes is often due to a sticking plunger in the foot valve.
