PROBLEM SOLVING !! RELAY VALVE LEAKAGE - AIR BRAKING SYSTEM ON VOLVO FM 440

PROBLEM SOLVING !! RELAY VALVE LEAKAGE - AIR BRAKING SYSTEM ON VOLVO FM 440

Peace be upon you, and Allah's mercy and blessings.
Welcome to the BIGGY FERI Youtube Channel

In this video, I will explain one component of the Air Brake System on Volvo FM 440, the Relay Valve.

On Volvo FM 440, the Relay Valve is used for "Relay Valve Parking Circuit" and "Relay Valve Front Circuit".
So both components are used the same.

If this Relay Valve is used for "FRONT BRAKE CIRCUIT", then

1 = Input (supply) of air from the front tank

2 = Output (Delivery) of air to the Brake Chamber on the Service side

3 = Evacuation (Drain)

4 = Air signal from "FOOT BRAKE VALVE"
For more details, see the video until the end ..

May be useful..
