moparx OP Buying your homeless and unwanted bolt on battery terminals Joined: Sep 2003 Posts: 20,742 north of coder	can anyone tell me the correct part #'s for the master cylinder & booster for a 1970 hemi cuda with power disc brakes ? the #'s i have are : master 2944476 and booster 2944486. are these correct ? if not, what are the correct #'s ? i'm assuming these are specific to hemi cudas only ? what are the differences between these and say a hemi b-body 69-72 ? thanks in advance !

It was used on '70-'71 hemi B and E bodies with power disc brakes. The earlier years hemi master cylinder has a taller and thinner reservoir.

Casting number on the master is 2230854. First off does anyone know what this is and secondly where I could find a rebuild kit for it.

That master cylinder uses the casting with number 3461187. I've had those two master cylinders side by side and the only external difference I see is that the outlet bosses on the one you have don't stick out quite as far. I haven't taken them apart to compare the pistons. However, I assume yours would also have a 1-1/32" bore, and the kit for the '71-75 disc brake Mopars would most likely be the one you need to rebuild yours.

The entire assy is HEMI specific, from the offset brackets to the deminsional mounting measurements of the booster, the Bendix dual diaphram is similar to the B/C body unit, but the rear stud arrangement and pushrod assy are quite different Mike 6970531-4345613-BoosterHemi.jpg (670 downloads)

I cannot remember which is longer. '.. it was long ago and it was far away, and it was so much better than it is today..' Jim Steinman
