all in and plumbed into the exsisting brake lines. I was running 4 wheel manual discs with all 3/16 line. I have not bled them as of yet (one man pony show) SHould i run 1/4 to the back or will the 3/16 suffice? With the truck running i'm having a very slow pedal return and feels like little to know actuation of brakes. With truck off i seem to get the same pedal action prior to conversion with having to pump 2-3 times to get strong pedal. Friend of mine says it's due to the 3/16 line going to the back. (added a prop valve while i was doing the conversion that it did not have before) Thanks for any input or tips as i miss not drving it for a week now!
