I am needing to replace my master cylinder on a 69 charger factory front disc brake car. I’m not interested in rebuilding the one I have. Just curious what other people out there are buying as an original replacement. This car isn’t ever going to see a racetrack or anything remotely close. If I could read the part number on the mc looking it up would be easier but it’s hard to make out. See pics. Any help in explaining the bore size would be be appreciated as well.

I’ve noticed that the two drum master cylinders I have are completely flat on the section that connects to the booster. So do the disc/drum MC’s have the ring around the center hole that sticks out a little? Probably not asking that in the best way. Attached are pics of my booster and of the drum MC’s I have and the last pic is of a disc/drum MC.

Strange. When I pull that part number off from Summit it doesn’t list charger on the car list.

Yeah that's strange, not sure what summit is up to.
Here it is installed on a 69 Charger

Power brake only masters do not have a provision( pocket with rubber bushing) to retain the brake pushrod used on manual brakes.
They rely on booster pushrod to hold plunger in location.
 
Oh N O it isn’t—- the “ in China “ is chopped off in that picture above…… of the “ Made in China “……

Well as long is

got it. Well as long as it works with the factory brake lines, this looks like a winner to me.

I had to use an adapter for the front line.. but the system had been hacked up with one of those shitty Chinese power brake kits , so I can't confirm what was original
