Mark, all that said I hope you get your brake "problem" worked out to your satisfaction.

"The Master Cylinder"

Enjoying life at the beach in SOCAL

I put that info up for Duck to help explain the dual circuit brake system. I am running Granada manual front discs and stock rear drums on my 57 Bird. Used the Granada master cylinder and a Wilwood combo valve. I don't miss the power brakes at all, they work great. Much safer and effective over the often scary front drums. Finishing up an alternator conversion this week if I can and after the holiday it's back to finishing the 445 Survival Motorsports stroker for the 65 Galaxie.

Just to add fuel to the fire, I read over on the HAMB (more than 1 post) that if your running just the stock drum/drum set up a proportioning/combo valve isn't needed.

I agree with Charlie too. After working on cars 40+ yrs when I would pull one in with a blown line, cylinder etc. you still needed a boat anchor to stop it.

Had a rear break line blow on my '74 Ranchero back in the day. Brake line rusted through and blew when I tried to make a rapid slow down to make a left turn. Had a tough time getting it stopped. Missed my turn. Would have hit anyone in front of me if there had been anyone close. Emergency brake on my T Bird could have not been much worse.

Dorman Products Part # MC 73323 fits a '66 to '71 Mustang with manual Disc Brakes and works Great with Drum Brakes on Baby Birds and does not need a Proportioning valve as it is self equalizing. The master cylinder with Power brakes Does need the proportioning valve however. Nice bolt up, however I suggest a 1/8" thick plate faced like the Original master cylinder to bolt between the new master cylinder and the firewall to stiffen the firewall when you install it and the push rod will need to be 1/4" longer then stock. You will be amazed at how well the Bird will stop still using drum brakes.
