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]
