1956 Ford Crown Vic in shop for brake work. Installed all new brake hardware, new brake shoes, drums and wheel cylinders. The brake line and hoses were replaced about 3 years ago. Also installed new dual master cylinder and new 7 inch brake booster. After making final adjustments, the brake pedal is lower than normal and braking is somewhat acceptable. If the pedal is adjusted any higher then the brakes lock up after little brake pressure.

I have used this shop for years and they are very good. They even compared my car to another client's 1956 Ford Victoria with similar configuration but has disc brakes and are stumped by the brake height being low. Any suggestions as to why the brake pedal is low?
