Front Brakes Hardly Working

Was your car originally a front disc car? If not you'll need the correct proportioning valve. Next question, what is the bore diameter of your master. It may be too large for your application. Larger bore requires greater effort. A 16th of an inch can mean the difference between stopping and slowing. On this site , someone has been good enough to post both parts lists and service manuals for our cars. I believe it was AbodyJoe, not 100% on that. Make sure you didn't accidentally get a "power" master where a manual goes. Also make sure your wheel cylinder diameter is correct for your application. Good luck.
