Newbie Question About My 70 RR Brake Master Cylinder/Power Booster

[soundhd]

Recently purchased a 70 RR. Below is a photo of the Brake Master Cylinder/Power Booster. Car has drum brakes all around. Car was restored about 10 years ago. Master cylinder has the larger well in the back. Is this a disc brake master cylinder? And if so, I do plan on converting to disc brakes...will this master cylinder work or do I need to replace it also?

thanks

Your booster is a Midland Ross and is for drum brakes. Your master cylinder is for disc brakes.

I dunno, the cylinder looks like mine but the lines exit out the passenger side of the cylinder. Front disk brake car.

66-70B with disc should have the Bendix booster. That small Midland was for 66-7B with power drum. In 71 they had a larger pancake Midland for disc.

So I guess the answer is just to be safe when I convert to disc (at least the front anyway) I should replace the master cylinder and the booster.........
