What's wrong with my brakes?

Changed front pads around 8K miles ago, just recently the brakes have gotten kinda spongy and doesn't stop well at all. Yesterday I started the truck, topped off the brake fluid and left the cap off, pressed brakes with the cap off, no fluid level change at all. Could this be a bad master cylinder or what? No strange noises, just doesn't stop well.

It could be a bad master cylinder or air in the brake system.

Check your rear wheel cylinders, when you adjust your drums. Often times when they leak they are the culprit for a spongy peddle.
