Check the caliper slides.
They may be "stuck".
You will need to remove the assembly and clean the rust from the bore.
Then lubricate everything with "Disc Brake Caliper Slide Grease" and reassemble.

As for the brake issue;
I like the Honda Master Cylinder route.
It is quick (you just have to goto the boneyard and get one with a small bore)
requires no booster
simple bolt in application.

Another thought.
look under your dashboard and see where the rod from your M.C. bolts up (actually it will use a clevis pin and retainer)
Can you move that pivot closer to the fulcrum of the brake pedal?
You may have to remove the brake pedal to drill a new hole.
The closer to the fulcrum you make the pivot for the MC rod, the easier it is to push the brake pedal.
IIRC most power brake systems use a 2.5/1 ratio whereas most non-power systems use a 5/1 ratio.
the ratio is a product of distance from fulcrum to point.
I.E. fulcrum to MC pivot = 1
fulcrum to pedal = 5
if you currently have 2.5/1 and you move the pivot closer to the fulcrum you change the ratio and make the brakes push easier.
Most MCs have a ball socket in the front so moving the pivot is not going to jam or bind (unless you get waayay up there).
