OPERATION
CHARGING BELOW 85 PSI (SEE FIGURE 3)
Air fl
ows through the trailer supply line, enters the trailer
supply port of the Bendix ® SRC-7000 ™ trailer spring brake
valve, sealing the anti-compound section. The air passes
through the quick release portion and out of the delivery
port to the spring brakes. The air pressure then releases
the spring brakes.
CHARGING ABOVE 85 PSI (SEE FIGURE 4)
Once the air pressure in the valve builds to 85 psi, the air
pressure fl
ows into the trailer service reservoir(s). The
trailer braking system is now in the normal run mode.
Service braking occurs through the trailer service relay
valve.
