You may have swelling brake lines in the front system. Older brake lines can have this problem, where as the pressure will balloon the lines instead of pushing hard enough to cause friction on the discs. Then again, one of the pistons in your front calipers could be stuck making it twice as tough to move the whole caliper enough to slow the vehicle, this is why there is a booster in the circuit.
But if the calipers are fresh and working well then I would look at the brake lines.
This is where there is some investigative work is necessary. Search the local brake shops for companies they use to have brake lines remanufactured. Or shoes or pads resurfaced, they will be glad to see you walk through their front door. Yes, you may be charged a bit more, but then you are only getting one set done. That's quite a company that will do one at a time and keep the price down. Many of us have these companies around us and we use them. If you would like their address that's not a problem. However, you may have the same capabilities in your town and it's less than the price of shipping back and forth from here in San Diego. And if the fear is the shop, check them out with the BBB, most companies don't stay around long without being on their list.
