I've searched a bunch of earlier posts and have been finding some conflicting information, so I'm looking for more opinions. I'm using a manual Disc/Drum set-up on my 69 Camaro street/strip car and plan to install an adjustable proportioning valve on the rear line. The one I purchased has 3/16 fittings. A lot of the posts mention using 1/4" line to the rear brakes, and my new rear flex line is 1/4" (splits to two 3/16").
Should I just run 3/16" line all the way and use an adapter at the flex line?
Would I be giving up any braking performance by not running 1/4" to the rear?
If so, would anything be gained by adapting down to 3/16 and back up to 1/4 at the prop block? Seems like the restriction down to 3/16 would negate any benefits of the 1/4 line.
Is there even enough difference to worry about between the two sizes?
