I agree with every else, that you may have a master cylinder, proporationing valve, or air in your lines problem. I've installed three of these ( 69 Dart, 64 Fury, and 70 Challenger) with no problems. The 69 Dart was changed from drum brakes quick. The first time I ever drove the car was down Thunder Valley Dragstrip and I didn't think I was going to be able to stop at the end of the track. I took the car home and there were three long stress cracks across the driver's side drum. I'm glad that drum didn't come apart at the end of the track. Gary F.

I have the same disc brake system on my 64 Max Wedge Sport Fury and they don't stop worth a damn. All new pads in front and good Semi-Metellic in the rear. I hate these brakes. I have to use a lot of pressure to get this car stopped easily. I do have manual brakes and have done away with the power brake system. I'm thinking of this summer changing to ALL 4 wheel disc brakes from Master Power or Engineered Componets I see advertised in Mopar Collectors Guide. Only difference I can see in price is with MP you get new spindles. It's scary sometimes if you have to make an emergency stop with the setup I have now. My .02 Bill C.
