what happens is the spring lets the fluid bypass, and you get that "sinking brake" feeling.

so how would you go about fixing this?

i bypassed it back in 1989. i never drove a vehicle with ABS before, so not having ABS was not a problem.
it still is not a problem. the only thing i have that has working abs is the crown vic, and i hate the brakes on that.
