but did you really do it correctly?? or did you push on the brake pedal and send the piston in the master cylinder into an area that is never used with a full load of fluid and then score the piston or the cylinder wall of the mast. cylinder???? or did you mess up and let air(or your helper let air back into the system when bleeding them??? you cant be in both places at the same time under the car by the valve and pumping at the same time? or did you use a hydraulic system to pressurize the brakes from under the car??
