Do I have to change the master cylinder if im converting my 63 volkswagon beetle from drum to disc brakes?

I have a 1963 Volkswagon Beetle, I purchased new front brakes so do I have to change the master cylinder from what would be a stock one for my disc brakes to work?

yes, the disk brake master cylinder has differnt capacities for the fron and rear brakes than the drum cylinder
Yes you also need a power booster that the 63 doesn't come equipped with. The disc brakes won't work properly without a power brake booster.
Yes you have to. The replacement of fluid id a lot higher.
yes, because your master cylinder holds a residual check valve (only for 4 wheel drum) that holds 10 to 15 lbs of pressure all the time. if you were to just swap to disc that would be enough pressure to cause the calipers to activate (mainly because the force being mutiplied up to 4-5 times based on bore size on the caliper) besides that you also have to install a metering valve... If you do not have one your rear brakes will not function until hard braking. Your rear drum springs have a hold down force of 125 lbs, therefor you have this metering valve that when you hit the brakes its holds off the front brakes until you hit 125 lbs to the rear then it will allow the fronts to engage. hope this helps
