I have followed these posts about disk brakes for many years as I would like to do the conversion. I have heard that using a late '60s early '70s dual master from a Corvette will work without power. Those Corvettes (from what I can gather) had non-powered disk brakes. Apparently, this master has a 1" bore. Now people are saying don't go without power, stick with drums. Just curious and would like more information and hear from anyone using non-powered disk brakes. I have a'47 1/2 ton with a 4 speed. I don't know if I have the ability to creatively engineer something.
Rusty, I would recommend buying a kit. I would not venture out and buy parts on your own if that is what you are thinking. The Master cylinder is a standard GM and they do use what is a called a 7" diameter "corvette" booster.
As far as booster or not. A booster allows for easier foot pressure. It does not stop any faster. It is nice to have while you are already doing the job anyway. That's all there is to the story.
Those who say drums are OK are correct for a standard truck. If truck gets "heavier" with Mods: motor, tranny, monster mudders or whatever, it may need Disc. Many like disc brakes no matter what the weight. That's all there is to that story.
The kits are designed for the DIY person. With the use of the internet, you will have no problems that standard tools won't solve.
In the beginning, ladies did not drive a lot. It was difficult to steer and stop. Too much effort, so engineers invented power brakes and power steering. Ladies were shown in all the advertisements after that, to sell more cars. Then "oh yeah, why don't we put that stuff on trucks too"
They don't stop faster or turn sharper. But really nice to have on a old truck.
