Maybe you can help with a new brake problem. I now have a good pedal but stopping the car is very difficult. It is acting like there is no power brake since I changed from an 11 inch booster and 1 1/16 bore master cylinder to a 7 inch booster and a corvette style master cylinder. I really seem to just have manual brakes with very little stopping power.
In my opinion, a 7" booster is just barely better than nothing. A 7" booster will produce less than half the boost than a 11" booster. And if you have a bit of cam, with low vacuum, it just makes it worse. The 1 1/16" bore master doesn't help either with a small booster. I have had some success switching to a 7" dual diaphream master cylinder in a case like yours, it still will not put out as much boost as a 11" booster, but it's much better than a single diaphream 7" booster. If that is not enough, you can change to a 1" Corvette style master cylinder, it bolts right in, and improves the mechanical advantage, at the cost of slightly more pedal travel.
