The Stovebolt Site Forums The Parking Lot Big Bolts 2 Chamber master cylinder bracket

I am converting my 6400 to a 2 chamber master cylinder for safety. Does anyone know if someone makes a backet for the master cylinder, or will I have to make my own? No use reinventing the wheel if someone already makes it.

Maybe something like this could make work?

Hy oldieoldie, I know there are many kits available with boosters, master cylinders, proportioning valves and brackets, I think most if not all of them were designed for trucks up to one ton. If those parts will work for what you propose to do I do not know. My advise is to buy a master cylinder with a bore that is equal to what the truck originally came with and buy the booster to go in front of it. Your truck probably came from the factory with a Hydrovac booster and that worked fine with a single system master cylinder, however if you go to a dual braking system the easiest thing to do is to install a booster in front of the master cylinder and boost both braking circuits at once. The only other caution I can think of at the moment is to purchase a master cylinder set up for drum/drum brakes, many of the kits sold today use master cylinders designed for disc/disc braking systems with these used in a drum/drum system ten p.s.i. residual pressure valves must be installed in each braking circuit, hope that helps.

Which master cylinder do you plan on using, and have you done your homework on the cylinder diameter and stroke, and the volume of fluid it displaces? If you get a mismatch between the master and slave cylinders your "safety" modification could turn a rig that big into a rolling deathtrap. I believe you'd be a lot better off rebuilding the original system to "as new" condition unless you've got the engineering and fabrication background to do it right the first time.

I'm bad with names, but I talked to one of the guys at the Reunion and bought a master cylinder/booster that he said would work. I just need to buy or build a bracket. I'd love to buy one if it is made, but I am able to build it if needed.

Thanks for everyone's input. I think I will mount the booster on the firewall with anew brake pedal from Ecklers. It says it works for 1947-1953, I wonder what is different with the 1954 that it won't fit? I have one of those too. It is part number 61-245607-1 on the ecklers site.

As others have said, the master cylinder kits for sale by all the vendors are for the 1/2 ton truck and will not work on your 2-ton truck...they don't push enough fluid to the bigger wheel cylinders you have...
