92 celica rear brake issue :-/

[KDMSHARK]

I've been workin on my cousin's celica, I was bleeding the brakes and came to the last one on the rear driver side. I keep getting A small burst of air when the brake is initially pressed but then a constant fluid flow as the brake pedal goes down. I was told to keep going until all air is out, but I've already bleed all the old fluid and new fluid is starting to come thru. And I still don't feel any resistance when I apply the brake. The brakes are drum and I'm not sure if it would be caliper issue or faulty brake lines. If anybody have any suggestion I'll appreciate it

try bleeding from (in order) Passenger Rear, Driver Rear, Passenger Front, then lastly Driver front. . then tell me if there is pressure after pumping
