I have a 69 Superbee, 383 Auto car, that I bought with an already in place front disc brake conversion. The calipers appear to be a factory chrysler part. So the car is stock drums in the rear, discs in the front. It has a manual master cylinder.

THE PROBLEM: You have to stand on the pedal super hard to make it stop. Can someone give me some suggestions please.

Thank you, Mike
