The system is all new, master cyl. calipers rebuilt, all brake lines and hoses
new. I've shimmed the master out 1/4 from the bulkhead, it still won't totally
release the pressure.
Maybe to problem lies with being unable to fit a single master onto one
requiring a  tandem model. The car body is a 67.5 with the recessed area for a
tandem cyl. My parts donor car was a 67 with an intact single cyl. I don't
have a tandem cyl. Or the manifold the brake lines connect to.
