Two more things to look for. On my '63 Fury I removed the power drum/drum brakes replacing them with manual disc/drum. First is the brake pedal which may have 2 holes for the pushrod. The lower hole is for power brakes, the upper is for manual brakes. Second is if you move the pushrod to the upper hole you'll have to adjust the brake light switch for proper contact with the brake pedal. The reason for moving the pushrod up is that manual brakes will need a little more leg muscle. Moving the pushrod up allows more lever action force. I used the Master Power Brake PR4722K adjustable pushrod.

Subject: swapping from power to manual brakes
Team,
I am removing the power brake booster from my '64 Fury to enable going to manual brakes. I believe the only to-do is to swap out the pushrod. (I already converted to a dual reservoir system.) I know Mancini and Mopar make adjustable pushrods. Anyone have experience with these products? Or, even better, is anyone planning the opposite (going from manual to power) and interested in a wonderful deal on a never-been-used booster? Hint, hint I want your manual pushrod...
Thank you,
Jim
