Agreed. I have locked all 4 up on my 66 Dart a couple times as needed. No issues here. Now I will say, a dual master cylinder would be safer and disc would help with the brake fade in the hills over by the Mississippi River but that's what downshifting is for! LOL You have to drive the car for how it is built. I don't drive it like a soccer mom drives her suv, cruising up to the stop sign and slamming on the brakes at the last second. :BangHead:
