Folks, I have a 1966 F-600 Ford truck that has a single master cylinder on the firewall, and a Midland remote booster on the frame. It has 5/16 brake lines, dual wheel cylinders on the rear and single on the front. The master cylinder is the wide bolt type, box shaped with 28825 molded on the side. Pedal hangs from the top with a single rod going into the cylinder. I am looking for some way to convert this to a dual master cylinder system with power brakes. It would be easier to go with a firewall mounted booster and dual master cylinder assembly if they make one that will fit and have enough volume. I have heard about a dual remote booster, and if that is all that is available, I'll go that way. I see ads for a kit to convert 66 model pickups to dual power systems, but I do not know if they will fit my larger truck.Also, I do not know if I need a master cylinder that has different sized chambers and pistons because of the different volume requirements between dual and single wheel cylinders per wheel front to rear.
Due to the size of the truck, a front disk conversion is not really in the cards.
As it stands now, I can lock up all six with no problem, but the master cylinder has flake rust coming off it, and the booster really looks bad. I could probably replace the master and the booster and make the brakes quite safe and reliable, but if I have to go to all that trouble, it would be easier to upgrade. WIth a firewall mounted booster, it would mean a lot less under the truck time. I have read here about the various different years and model setups that will bolt up, but again, I don't know if the will fit my bigger truck.
Thanks
Jay

 

Bump. Fellows we need to work on this unanswered post.

first thing I would try is the MC and booster from a mid 70s F600. you'll also need the proportioning valve

 

We need to decide which post to answer!!
