We Have Had The car For 2 Years - We Have a 1970 Chevelle With a 4 Wheel Disc Brake Conversion and It has Always Stopped Great - I Mean Great

The car Has A Crane Vacuum Reserve Bottle

The Master Cylinder Was Rusted - So We Sent It Into The Shop To Get Painted And Reinstalled - Thats It

After Re-Installation The Car Will Not Build Vacuum :(

Vacuum line off to can or booster?
