Guys, My breaks were kind of mushy and I just figured it was a leaky rear brake drum cylinder. I replaced both cylinders since they were cheap. I also replaced the rear shoes, drums, and master cylinder(also cheap). I blead the brakes and they still feel the same! The car will stop, however the peddle it is almost all the way to the floor. I can hear that wooshing sound from the brake booster too.
What should I check?

If you have checked all around for leaks and there arent any, my guess is bleed the brakes some more.

OK I checked for leaks and there is no leaks in the system. I re-bled the brakes and I have peddle, ONLY when the car is off. Once I start the car, my peddle sinks all the way to the floor.
Whats the problem! I dont think the grommet on the booster check valve bleeding because the car does not change rpm at idle when I press on the peddle. Is the brake booster bad?

I doubt it but it is possible. I wonder if the master cylinder itself is bled all of the way, if you have changed that recently.

Well, I just found the problem and both you guys and the mechanic were right. Rear drums have two different size shoes. The smaller ones go to the front, and the bigger ones go to the back part of the drum. In my haste to install, I put both the small ones on one side and both big ones on the other. DUH!!! Thats why the brake were uneven as you guys stated, and I didnt have peddle. Live and Learn
