With the Wilwood Brake Proportioning valve you recommend purchasing two Goodridge adaptors G-816-03P to fit this valve into 3/16" copper pipe or to braided lines. What fitting do I need when working with 1/4" brake lines?
For 1/4"you will be better off using Goodridge adaptor G-815-04P and C-BBU-F-4.
