1992 Buick Park Avenue Question: Power Brakes

Due to many miles on the car, my power brakes are failing. The pedal fades with foot on brake and car rolls until I apply more pressure. How do I get it fixed? I've had my brakes and brake fluid thoroughly checked so don't tell me that is what is wrong! -
Answer 1
It would be very difficult to know what is wrong without seeing the car in person, but I have a question, is the pedal sinking to the floor? Would you describe the feeling of the brake pedal as "Soft", "Spongy" or "Hard" when you apply the brakes? -
Comment 1
To lawrenceg: Braking is normal at first stop, then pedal fades 1/4" to 1/2" (not to floor), car rolls, exert more pressure on brake and car stops moving. When it is quiet i.e. engine not running, You can hear a "swoosh" when applying brakes -
Answer 2
U have a leak in your brake system somewhere air is getting in your lines. U need to check for leaks and bleed your brake system. -
