no rear brakes

Well here is what's going on I replaced my rear brakes and i noticed i have a no pedal till i hit the fronts.so pulled the wheels had my brother hit the brakes and i tried to turn the drums and they turn Free so I check fluid level good there. Bleed breaks good still no breaks. It is an 84 f150 nothing special with break system. I did wheel cylinders thought they leaked was going thorough fluid like crazy, shoes, all the springs, and drums any more info let me know and thanks for the help

So they're frozen? You can't move them at all by hand or with a flathead screwdriver?

Okay, you need to adjust them with the drums on throughout the small adjustment hold on the backing plates. Jack up the rear of the truck and put it on axle stands. Turn the star wheel adjusters on each brake just until you can turn spin the wheels by hand and hear a little bit of brake resistance/rubbing. That will adjust the shoes out so that they'll contact the drums.

When you bleed the cylinders you dont have pressure? But the front brakes are working. You keep saying your going through a lot of fluid.The brakes are a sealed system if the fluid level in you resivor is dropping you ha e a leak somewhere.

You are doing this by yourself? That's not going to work. Get a significant other out there to push the brake pedal while you work the bleeders in the rear.
