Folks, I have a chance to get a booster for free, but came from 1970 with disk up front, I have drum all the way around, is there really a difference, same question with master, why would
they be different, same job, push fluid. Thanks Mike.

The booster might work but the masters are different disc and drum. Also manual brakes use a smaller piston which applies more pressure so if you want power drums you might want a different master. I had a 66 Chrysler 300 with power drums and they worked very well.

The master cylinder may have the same job, as you say, pushing fluid. But not the same amount. Disk brakes generally need more volume moved, especially with multi piston systems, meaning that your drum brake master will run out of travel before completely pressurizing the front brakes.
