How far does your brake pedal now move before the brakes are fully locked? If there is room for it to travel further, and if your pedal assembly is adjustable, you may be able to get some relief from the heavy pedal force.

Check to see if your brake pedal will allow you to move either the pivot point for the pedal or the connecting point to the piston rods. If you can change the mechanical advantage on the brake pedal so the piston rods move more slowly as you depress the pedal, you can make it easier to press the pedal. But you don't want it adjusted so far that you can't get full brake action before the pedal runs out of travel.
