I have a 79 MGB I have installed new front brakes(rotors etc,) new rear brakes), shoes cylinders) and a new Master cylinder. I have bled the brakes many times and I still have no brakes. I can pump the pedal and it will maintain pressure for a while but after I release it I have zero pedal again. I just purchased a EEZIBLEED from Moss which is really helpful and I have used it to bleed the brakes and they feel a lilltle better but I still do not have enough breaks to stop the car. Any help and or information will be greatly appreciated.
