1995 Pontiac Bonneville

Just bought this vehicle, it has had extensive brakework 4 months ago and then was apparently sitting unused for most of the time since. It had a new master cylinder, rotars and brake pads all around. The brakes obviously needed attention when I first drove the car a couple of days ago, the pedal went all the way to the floor and then pumped up. Itook it in to a local experienced mechanic, they bled the brakes two or three times in an attempt to rmove all tha air. Seemed ok for a day and now they still require pumping up to function. Is there something these mechanics are missing? Thanks for your help.[/B]

They probably should check the seals for the new master cylinder. Air is getting into the system.
