Well, the parking brake and brake fluid level share the same indicator. If the indicator is lit on the instrument cluster and the parking brake is released, you should check the brake fluid level in the master cylinder.

If the level is low, don't just top the master cylinder off. It is low for a reason. Either you have a leak, or the pads are worn sufficiently enough to cause the level to drop and the light to come on.

The parking brake shoes are contained inside a drum formed by the brake rotor hub. The parking brake assembly is a drum style brake, the regular brakes are disc.

As for the difficulty of changing dash lights, are you asking because you thought about just removing the Brake bulb, or for other reasons?
