Quote: Is it possible the 1 1/32" MC does not provide the volume of fluid needed to make the calipers more aggressive?? You said it used to dive with the drums, which to me means it had substantial front brake. Calipers do require more fluid volume than a wheel cylinder don't they?
Car already had a disc brake master cylinder on it for the last two years. It is a standard disc brake unit used in millions of Darts, Dusters, Valiants, 71-74.
A 1" bore would increase the pressure but at the expense of more pedal travel.
The pedal is not solid (unless the line lock is on) as it should be and its taking excessive pedal pressure and travel to get the car to stop quickly.
After sleeping on it I'm convinced something is flexing. Maybe one of the caliper slides are tweaked, seals are junk or hoses are no good.
I can swap parts off the Duster, heck I can swap the calipers, brackets, rotors and pads over if need be in an effort to isolate the problem.
