    what do i need to rob from the 96 for rear discs

    Besides obviously the entire rear axle (gonna just unbolt the arms from the frame and do bushings while it's out because why not) what will I need? Discs and drums don't really work on the same level of pressure.

    Can I keep my 1990 master cylinder? I'll be running new lines/flex hoses all around anyway.

    several folks have just swapped the rear axle and mated up the parking cable and brake lines and been done with it and had nill issues.

    personally I'd rather swap to the aero non-abs booster and master just to get the better braking feel.

          Aero parking brake assemblies are available new yet. In case you were wondering.

          I personally, would want to have functioning parking brakes. They will stop the car if need be.
          1990 MGM: $50 E7 heads, HO cam, Holley SysteMAX lower intake, HO upper intake with an Explorer TB. LSC ECM. Lincoln logs into stock dual exhaust. K&N drop in air filter. Wide ratio AOD, 2400 converter with a 3.08 one tire fire out back. Car is less slow now. Then there's the '92 Beater. Dual 2.25" exhaust with shiny tips. Rumbles nice. Super slow. Burns oil too.

            Good point about the pressures. I have an 89 so 90 may be different. I removed the combination restrictor/residual pressure valve from the master cylinder. This looks like a plumbing fitting that the rear brake line screws into at the Master cylinder. The "fitting" then screws into the master. This was done for 2 reasons. The restrictor component functions like a proportioning valve and reduces the pressure for the rear brakes. The residual pressure component keeps a few pounds of pressure in the rear brake line. This residual pressure is needed to increase drum brake response time but is not used with disk brakes.

            After removal of the device, I removed all interior components and reamed out the restricor a bit, just a couple of drill sizes. Thinking I might need to control the rear pressure I added an adjustable Wilwood proportioning valve in line to the rear. The new valve is now cranked all the way open.

            I did keep the original Master.

              You can use the old master cyl, but I'd go with new ones for a rear disc car if at all possible. REplace the booster while you're in there. The later one has more surface area for effectively more assist. It doesn't make the pedal twitchy either, which is a good thing. It just requires less leg effort in a panic stop situation. Overall, when we got rid of all of the original brake system plumbing and valving and swapped it over to late model stuff, the car stopped a hell of a lot better. It did well before, but its more even feeling now. No dive problems or anything like that, it just stops without any loss of control.
