did it feel spongy before repairs? it's a notorious issue, but harmless.
otherwise, got air in lines, bleed the system.

Make sure you adjust the rear shoes with the drum on and make sure there is a slight drag on them. That will bring the pedal up a little higher. If you were able to slip the drums on easily and didn't adjust them, that is the problem.

I agree with this..also... the drums must be adjusted to drag slightly on the shoes then back off 3-5 clicks...with all you have done the brake pedal should be high...

air will cause the pedal to have a spongy feel..
