    Dons recommendations are spot on for re-lining and converting to a duel circuit drum/drum system.

    I totally support any person NOT doing something they know is outside of their ability, That is a higher level of professionalism respected and honored in the work I do.

    The instructions I provide are for converting the FRONT AXLE to disc brakes. All the other information on my instructions is just "help full information" that is "general" and covers all G vans from 64 to 70. Since there is a million and a half differences, "depending on what you plan to do with your van". I do not plan for anybody else, the installer is responsible o know what they are embarking onto for the rest of whatever it is they are planning for their brakes.
    Figuring out which master cylinder and valves you need is the ("you have to do some research on and know what your getting into") part. If you have specific questions about which master cylinder or which valves to use for what you are building you can always email me and I will help you out.

    Also said "there is no out of the box bolt on kit" .

    My instructions do not talk about or quote anything on brake lines or fittings. I figure that to be so extremely simple it is four notches lower then basic, if one can't deal with connecting up brake lines on their own; then modifying and customizing their brake system is something they need to hire experienced help with.

    Residual vales are best connected right off the master cylinder ports before all else.

    Which line the front or rear circuit connects to on your master cylinder is something you need to figure out. There is definitly a correct way to connect them and master cylinders are not all the same. If you don't know you have a 50% chance of getting it wrong.

    When it comes to line fitting sizes you can get lines with different size nuts on them or you can get step up and step down adapters that are actually quite common and come with new or rebuilt master cylinders other then the cheapest master cylinders.They are common because several different cars might use the same master but some use one size while others use another size line nut. You can see those addapters used here (two different ones on the same master). No i don't remember the part number but any parts guy older the 19 should be able to get it for you if you tell him what sizes you need to adapt. They have an inverted flare cut into one end so they thread directly to the master cylinder.

    I hear you Ditdater. This needs to be my next project but I am wary of doing it by myself. I can take everything apart, and probably install the new dual MC, and put the lines in place, but will need help making sure everything went together correctly, is sealed etc. And it's been decades since a friend showed me how to bleed brake lines. Also, I have a sway bar so I will need help with fabricating the spacers for that. I'm building more confidence with each project I complete but like Don says, brakes are pretty significant.

    Post by Joe Van Mon Feb 11, 2013 3:25 am

    Awesome pictures and info I am getting ready to do the conversion too I have the master out cutting the bracket is no problem but I see a big problem with my sway bar. I cant move the bar forward because its too close to the radiator and making the a drop down spacer it is still in the way the only way I see it working is put the sway bar behind the radiator? instead of in front OR do away with it all together since the plan is making a gasser with the 4 inch re arched springs and the front sitting so high you almost need a sway bar I don't want to leave the bar off but I also don't want to use the single master either.Any info or pictures of a modified sway bar bracket left side would be highly appreciated since I am in the middle of this project. ...........THANKS....JOE VAN.........

    The problem I am having is the duel master cly is hitting the sway bar I have seen your pictures I will try to find it and study it better the master looks the same as donivans and his is above the sway bar mounting bolts unless I have a after market sway bar???? but the mounting place should be the same THANKS..........I looked closer at donivans and your right I think the 2 inch spacer will work thanks again back to the garage.........................

    THANKS you guys were right I dropped the sway bar down 2 inches and it went right in I guess that spending too much time in the garage will keep you from thinking straight the pictures tell a thousand words...................

    Post by Joe Van Tue Feb 12, 2013 5:13 am

    This is a fairly easy conversion and well needed for someone who has a single master and some mechanial abitily I own a brake and tire shop here in Florida est in 1987 I have had many people that try to save money witch is understandable but when it comes to your brakes leave it to the someone with experence you can do more harm than good if you have no mechanical ability just like I would not attempt to paint a van becuase I am not a painter. Do not be to proud or afraid to ask a professional the life you save might be your own.I brought my 1975 chevy van STOW-A-WAY to a car show this weekend and won peoples choice chalk one up for vans...my friend has a 61 bel-air wagon that has a single master he told me the fun ride he had when the brakes went to the floor advoided 3 cars and wound up in the bushes my other friend said last week his wife ran in the back of his 47 ford pick up with his 48 ford pickup also with single masters when the pedal went to the floor needless to say saturday I pulled the singel master off.

    Fantastic post donivan, thanks for taking the time to diagram the plumbing and take pics. You have made it crystal clear. I think I am going to try the copper/ nickel lines and cut and flare to fit.

    Is there a part number for the rear rubber hose? I called Advanced and they say it shows 2 for the rear, both same part number but they are discontinued. Is this just a generic rubber line?

    I also have a broken spring, the bottom one that goes between the 2 shoes. Is there a replacement for these? I am having no luck with any of the parts stores around here.

    Thanks for the part numbers. Got the spring kits but the hose a no go. Will order from link.

    Should be noted that with the steel lines listed I needed an adapter. The steel lines are 1/8 males and the hose is a 1/4 female.

    I am thinking that the 1st Gen Sportvans, or at least the 66's, use a 2nd Gen brake hose at the rear axle and the new 3/8-24 brake line won't screw into it,,,,,so it needs an adapter to to connect it to the 7/16-24 brake hose,,,,,,,

    Yes, I got that part at CarQuest, but I'm sure others carry it. My 66 Sportvan (Deluxe!) had a larger line in between the PS Tee and the single rubber line in the rear. No matter what you do, don't mess up or lose the rear Tee!!

    This is what mine WAS before the upgrade, now it's all lines from Don's diagram/parts list, except that adapter for the rear brake hose. I got the hoses from O'Reilly, and as far as I could tell, late 50's thru early 60's pickups had the same setup in the rear. O'Reilly has been pretty good at having a correct part when I key in a 66 G10.

    I would say #3 T is 7/16-20,,,,,and both hoses are 7/16-20 outlets,,,,,HOWEVER,,,,,,the inlets are different and you use the adapter if you got that 7/16-24 inlet on your hose,,,,,,
