You will notice a tremendous change by going to 3 wheel disks. When I built my WC-53 Carryakk back around 2003 ?? I was running out of time to have it road ready for the Iowa Rally. I took a short cut and did not use a hydroboost
brake booster. Around here on the back road all seemed well so Off to Iowa Rally we went with the Carryall on my Trailer. Quickly, with the Carryall on the ground and driving it all over, I realized that I had a TERRIBLE problem with the brakes. The problem, I could not stop it in a emergency or a quick stop in traffic. For the week we were at the rally I drove it very little, now knowing I had serious brake issues. First thing on getting home was to add hydroboost. Once installed the Carryall would stop on a dime equal to my 1 ton Ram/Diesel
pickup. Never again, hydroboost went on all my Dodge Old Iron/Diesel builds.
You could run 3/16" brake lines like Detroit does on most cars/trucks, But for the small difference in cost I always used 1/4" steel lines. You WILL need a proportion control valve. Go to Summit racing, them have them at realistic
prices. Once installed at the Master Cylinder rear line and adjusted properly , you will never have to touch it again.
Your welcome to call me and discuss this on the phone, send me a email and phone number and good evening time to call
