SR-2/4/5 Trailer Spring Brake Valves
What are the defects?
The moulded rubber face of the Inlet/Exhaust Valve ('I/E Valve') component of the affected SR-2/4/5 valve assembly can crack and separate from the valve's metal insert. Air can be trapped by a separated I/E Valve causing it to balloon and block the exhaust.
What are the hazards?
Problem can prevent the application of the parking/emergency spring brakes on the trailer during parking or in the event of a trailer supply line failure.
