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 am very curios Matt, what master cylinder and proportioning valve did you buy?
