I have a 72 b-body with the power disc brakes. I may be crazy but I want to get rid of the power brakes and go manual. anyone ever done this? do I just need to remove the booster and install a manual master cylinder?
My 70 Charger had 4 wheel drums when I got it. I added a 1975 Dart power booster & MC and the 11" front discs. Everything was a bolt in deal. Many years later I decided to switch to a manual MC. I had a few things wrong and because of that, the brakes felt terrible. Hard pedal with minimal brake force. I wimped out and put all the power related stuff back on.
Now, 4 years later, I am ready to try again.
If you have rear drums, this should be easy to do. I'd go no larger than 15/16" on the master cylinder though. The bigger the bore, the harder the pedal in many cases.
