I have an EM replica with Corvette suspension and manual disc brakes all around. I also drove a somewhat heavier 1963 Corvette coupe with manual drum brakes for many years. Both cars stop very well. My point is that you may not need a new brake system or power brakes to get it to stop well. Since you don't seem to know much about your car, I suggest you start by locating someone near you who can identify and troubleshoot your brake system. That likely will not be a standard mechanic. You need someone who has built some hot rods and/or race cars.
