I got the MC/booster combo from O'reilly's and I ordered it for disc/drum.


That's your problem. You will never get the brakes working properly if you're using a master cylinder designed for rear drum brakes when you're actually using rear disks. You NEED a Disk/Disk master cylinder. That will solve your problem.


Nope

The only difference is reservoir capacity, just check it when doing an oil change, top off as needed and the residual pressure valve in the rear brake (front port) outlet, which he's already been told to remove.


Even removing the built in residual valve won't make it safe. There is no way I would use a disk/drum master cylinder on a disk/disk system. As the pads wear the pistons have to make up the difference and need larger amounts of fluid. That's why the reservoirs are larger on the disk side. It is ALWAYS best to use a master cylinder designed for the type system you're using. Jury rigging brakes is never a good idea.
