I have a 60 Pioneer with power brakes single master cylinder. I want to upgrade to the dual cylinder for obvious reasons. If anyone has done this, I would like some help with the correct parts list or info on such. Thanks
I did mine with disc brakes but if you're staying with drums than use a dual from 1967-1970 full size Chrysler (Bendix 11323). It will bolt on and still fit under your original booster.
You will need to modify the brake light switch. Some people have used a T fitting but I just made a bracket and mounted it on the brake pedal using a switch off a later model vehicle.
After that, it's just rerouting the rear brake line from the junction block to the new master cylinder.
