Another question for you. I am also looking to install my brake pedal on my 40 ford Coupe. When looking at Fatman Fab, they sell their chassis with a standard, not power system, and they claim it is adequate for front disc, rear drum applications. I was planning on a 7" booster with a master from a mid 70,s Mustang 2. I do not want to cheap out now and regret it later, but on the other hand, like Fatman says, it takes up less real estate under the car and I do not want to overbuild the car. I am running a Mustang 2 front end. Again, any help would be greatly appreciated. Thanks, Chris
I built a 1939 Ford convertible back in the 80's and although I didn't have a ifs I did have disc brakes on the front & drums on the rear. I used a double master cylinder and no brake booster,I drove the car thousands of miles and tje brakes were never a issue,I honestly don't see how not using a power brake booster could be considered a safety compromise.

Here's how I see it In order for what I say to hold true - First the system must properly built and sized. The main difference will be how far you need to get your foot up onto the pedal, that's due to the pedal ratio. A booster eats up space but you can usually keep your heel on the floor board and pivot between brake and gas. Dropping a size in MC bore will take less less leg force to generate equal clamping force at the wheels. As always you need to be mindful of the displacement of fluid needed and what you'll loose. Many many many times the exact same master part # is speced for both power and manual brakes. Also many times The designation for drum/drum or disk/drum or disk/disk is because of the presence or lack of the intrigal residual valve in the master assembly. Btw it pops right out of there
if doing a new set up would go with power booster - never know what situation may come up where a little extra help will come in real handy. no matter which set up that you go with regular maintenance is just as important.
If you can't lock the brakes w/ a 6:1 pedal ratio w/manual brakes , something is wrong w/the brakes or you're awful puny ... dave
You didn't mention the engine. Does it produce enough consistent vacume to operate a booster? Also, who will be driving the car? If my wife were driving it, she'd probably prefer the booster.
I have MII and manual under floor bks. I can stop the car but it is usually a planned stop. I have not been satisfied with them. Have put in harder pads and still not happy. I think we get used to daily driver with power assist and would like the power assist. in the rod. It is a personal feeling coupled with how u drive and what u use the rod for. And how much work and money u want to spend. You can go to larger rotors 11" and that may bee better. I will try that someday.
