Master Cylinder question.

To be honest you would have much better brakes and a better pedal if you would have switched to the 2-bolt design. I got an aluminum MC from NAPA for a '80 3/4ton Dodge ram. I used the 4 bolt - 2 bolt adaptor and the new MC. My pedal feels just as good if not better than the PB set-up on my Cummins truck. I used to hit the 2nd turn off road and not I can easily hit the 1st turn off road.
