Just blowing thru this post, Power brakes I assume. If you checked everything else check the adjustment rod on the power brake booster the one that goes into the back of the master cylinder, if the rod is to long the brakes will not release correctly, You are only talking a maybe .010 to .020 of an inch will make a big difference...

yea but everytime that i ordered that part number from auto zone, advance, or orilieys, i got it looking like what i posted. Can someone with a factory disc brake 70 chally chime in here. I didnt get to change it this weekend, i will have to do it wed. sorry bullitt.

Dont worry about me.....If your brakes are working properly maybe you should leave well enough alone. Whatever you do don't put the drum MC on as it should have residual valves in  both inlets which would cause your disk brakes to drag.

i have to find out if the one that  i have been getting is the right one or not. I have ordered it through multiple sources and it keeps coming in looking like this. always the same thing, 1970 Challenger RT 383 4 BBL Front disc rear drum.

the nmaster cylinder witht the equal size reservoirs & two round tops is correct for 70 , yet another different part for 70 only

This is what cadone sent me is the differences in the two MCs other than physical appearance.

The difference between these master cylinders are the bore sizes: The 10-1326 is 1"
                                                                                                       10-1515 is 1 1/32 "
