Manual brakes, adding a brake booster

[lowandslow1965]

Folks, I need to know if I can add a brake booster to my manual drum brake polara, I just want a little nicer brake pedal. If so, any suggestions? Affordable, simplistic, functional, is where I'm hoping to go
Thanks

Yes you can do it. The brake pedal for a manual car is different as the linkage for the master cylinder is attached farther up to get more torque. The master cylinder might or might not be the same depending on the year. The mount for the master cylinder is usually also different for a manual car owing to the slightly higher placement of the master cylinder. Your best bet would be to source the correct parts from a donor car. You would be advised to have the brake booster rebuilt so avoid problems with a used unit. I would suggest that you also source the correct new master cylinder for the same reason. www.powerbrakebooster.com does a good job of rebuilding brake boosters.

I have an NOS Mopar manual to power brake conversion assembly that I believe is for a 1967 - 1968 C Body. This is an entirely under the hood assembly that has a master cylinder, brake booster and an adapter bracket that pushes the booster away from the firewall so you don’t have to change your brake pedal. I will take & post photos later today.

Into probably the early 1970s, there were factory "add-to" power brake and power steering kits for the dealers to add to cars to that were not ordered with those options. GM did it too.

Install a smaller piston bore master cylinder for easier peddle feel. Larger piston bore harder peddle, smaller easier with more pressure. Should be less than 1" in your car now. 15/16 is a good start.

Okay, while maintaining manual brakes, not adding a booster of any sort? This sounds up my alley

Jeez I wonder if this would work in the previous years as mine is a 65

Yes, no adding booster. Much less cost and time to try the master swap before redesigning the system. You will have more peddle travel with more pressure to wheel cylinders. Don't put your self through the windshield.
You maybe able to measure the bore size on the current master to see what your working with.
