Electric Brake Booster?

[JEB 44]

Has anyone looked into (or actually installed) an electric brake booster?
I think it might be worthwhile but would like some real world experience to find out for sure.
Thanks in advance for any responses!

I've installed the new FFR brake booster that is vacuum controlled

Yes, had them on my old car. At first, a lot of issues that ultimately I found to be caused by header heat. Once I resolved that, they were like my daily driver. You can find them here: https://abspowerbrake.com/collections/electric-high-power-master

Thank you for the informative response. I appreciate it. I'm just starting my truck build but waiting for many backordered parts has me twiddling my thumbs and looking for other things to work on (i.e. figuring out my brakes, finishing the engine/transmission etc)

Haven't used electric, but Whitby makes a really nice vacuum booster solution for these trucks. I have
used three of them, they are excellent.

I'll offer another opinion.... you don't need power brakes. My build did have the Wilwood big brake kit. With our vehicles weighing much less then 3000 pounds, non-power brakes are just fine.

While I agree that you don’t need power brakes, I would have actually preferred the power brakes feeling on my roadster. The brakes are great but I prefer the boosted pedal feel.

It's not a matter of being able to stop the vehicle. Ultimately it is the tire traction that is going to determine how hard you can stop. The advantage of power brakes is how easy is it to modulate the brakes at the point of brake lock up. If it takes nearly all your leg strength to get the brakes to the point of lock up you can't comfortably modulate them. That is where power assist makes a huge difference in how easy it is to modulate the brakes.

I ran across a web page that has an article on how to design a braking system. It included a spread sheet that takes into account the leverage ratio of the brake pedal, diameter of the master cylinder bore, diameter of the caliper piston, number of pistons, rotor diameter and overall diameter of the tires. It would also would take into account the multiplication ratio of a power booster if you were using one. The spreadsheet would give you a dimensional less number with a range that most people would consider the brakes to be comfortable. Above the number it would take to much effort to be comfortable and below the range the brakes would be to touchy.

I ran the stock Mustang GT brakes with the Wildwood pedal box with dual master cylinders through the spread sheet. The number that came out was way over the upper limit for comfort. I wound up going with the 13"/11.65" Mustang Cobra brakes which got me close to the upper limit but still over.

I would love to but I can't find the link. I would think if you search on brake design you will find the same info from more than one source.
