Proportioning Valve
Good advice mainly.
There are two styles in A's with Factory Disc/Drum Brakes!
In 1969 the style used for Disc/Drum was a separate hold off "Texas" valve about 10" down the frame rail from the main distribution valve.
In 1973 it was combined in with the distribution valve! "Combo Valve"!
First I would make sure my Bleeder valve on the caliper is always to the top! Old Hoses and line can be an issue as well as any other brake components!
Examples of 67-72 and 73 up valves! BB cars need the heat shield so swapping a 73 up in the earlier BB cars does not work to well as the bolt up is not the same! JMO!
