2001 Dodge Caravan brakes problems

Landmark dodge realigned the front end and replaced both calipers during a three month timespan. This did not eleminate the problem. I contacted the manufacture, and was asked to take the vehicle to champion crysler for a second opinion. I did this. They told me that the alignment was way out of specfications for this vehicle and they reset it to sepcs. I then was asked to test the vehicle to see if they had made a change. I did this. While testing the vehicle a large ford pickup pulled out in front of my wife.

The vehicle had an on-going problem when applying the brakes. The pedal goes to the floor and pulsated. This resulted in extended stopping distance. The dealership indicated to the consumer that the problem was the master cylinder, but no parts available at that time. The consumer was too nervous to drive the vehicle. There was no prior warning and or the brake light did not indicate that there was a problem.
