Getting ready to switch out my 62's brake system from single cylinder mc to a dual disc brake master cylinder.
Question- can I use the pedal rod with the new mc or do I need to find another one? And if I have to use another...where can one find one? Thanks.
 
Are you staying with manual brakes?
If you are converting to power brakes you will need a fulcrum linkage. (They are easily found on FBBO, for about 75$)

IF you are staying with manual then you should be able to stay with your pedals/linkage.
If I'm mistaken hopefully somebody more knowledgeable will chime in.
 
if your going to a 2 bolt master cylinder you'll need the adapter. you should be able to use the original push rod. a 15/16" master cylinder will need a modification to the rod. a new distribution block and coupling will be needed to complete the conversion. these are available from the line re-pop folks.
 
Thanks for replies. I'm sticking with non power and a 4 bolt cylinder. I just ordered the distribution block and dual lines for inline tubes and have a disc brake proportion valve from another car.
 
I switched over to manual dual master on my drum to disc switch. I bought a adjustable push rod. Turn into a pain in do-pa. I'd go with the stock push rod first. On the end of the stock push rod there is a bump that comes in contact with the brake light switch. Adjustable rod didn't have it. Had to buy a buy a brake light switch with a lot of thread to adjust it and made a new bracket for it. To stubborn to change to stock push rod after buying the adjustable one. A pic of the switch I put in.

Call dr. diff, he can sort you out. That guy knows his ****!
 
It seems that this is a common enough upgrade that it should be an easy answer.
I have owned only 2 cars with the deathpot single reservoir. I kept them stock since I was selling the cars as stock as possible to get the most money.
My friend had troubles in his 64 Valiant when he swapped to a dual circuit master cylinder. He had a bunch of trouble getting all of the air out of the lines. My guess was that the stock deathpot MC had a shorter working length and used a shorter travel inside. I believe he swapped in a longer pushrod and was able to fully bleed the system.

i have the a-body discs and 11" drums in the rear on my 65 coronet. i don't use the proportion valve. don't go any bigger than a 1" master cylinder.

You haven't noticed any issues with line pressures without a disc brake valve?
