Front disc brake conversion question
 

Installed a Stainless Steel Brake Co. front disc beake conversion set-up on my '68 Chevelle. All done except for installing the adjustable proportioning valve that came with it. Had to get adapter fittings, etc. But not sure how to go about setting the adjustment. Also on a '68 does the rear master cyl chamber go to the rear brakes?
Thanks. Dave

Small reservoir is the rear large is the front.

Adjust it to rear and slam on the brakes. If rear slides adjust toward the front until rear stops sliding. Then they are balanced.
