spongy brake pedal

I just recently replaced all of my breaks front and rear with new disks, drums, calipars, wheel cylinders, pads and all of the hardware kits available! but the problem is that the brake pedal is still spongy and all of the lines have been bleed and my brake light is still on, the breaks work real well and there is not alot of pedal travel.... oh and also I replaced the rear wheel cylinders with the larger chevy ones for better rear breaking. Any ideas why the pedals still spongy and the break light is on.

from what i understand the brake light comes on when a low vacuum is present. did every line get bled enough and in the right order? RWAL proportioning valve inside the frame rail on the driver's side just above the rear axle, right rear, left rear, right front, left front. did you adjust the rear shoes?
