You do not say what year or model it is, but even though you bled the front brakes, bleed the backs too-braking system are diaginal so a front caliper is paired with the opposite side rear brake so that if there is a failure you have better control. This is especially in older vehicles (more than 10 years)-that being said, make sure there is not a leak in the hose or the plastic fitting going from the top of the engine to the brake booster. Use a can of carb cleaner or throttle body cleaner, and with the engine running, spray around the hose where it comes out of the booster, all the way to the engine-if the idle changes at all, it has a leak. It is possible the booster has failed, and worst case you will need to replace it, they are not real hard to replace and depending on what year and model/engine, usually less than $100.
THE POSSIBLE FIX FOR THIS IS THE VACCUM BOOSTER BUT COULD POSSIBLY BE THE MASTER CYLINDER ALSO THESE TWO PARTS WORK HAND IN HAND. I WOULD RECOMMEND GOING TO THE SALVAGE YARD AND PICKING UP THESE PARTS AND TRYING IT. IF THIS FIXES YOUR PROBLEM THEN OFF YOU GO
