Brake warning light on after brake job??

[BigRed]

I'm a rookie to drum brakes. Seems like all the trucks I've owned have all had new rear brakes. However, my burb does not. So, I put new shoes, wheel cylinders, and spring kits on the rear today. I also had the drums turned.

Anyway, now my brake warning light is on. Is this probably just an adjustment problem? I tried to get the hubs on there snug using the adjustment piece at the bottom, but maybe not. I also bled the rears again to see if that was the problem, but that wasn't it.

That brings up another point, whats the procedure you guys use to bleed the brakes? I had someone pump the pedal several times and then he held the brakes to the floor and then I opened the valve until there was no more spitting. However, it seemed logical to me that fluid should still have been coming out as he was holding it to the floor until I closed the valve. However, it didn't.

Thanks!
