Sure. Sometimes it's integral to the master cylinder. But some master cylinders have a separate brake fluid reservoir that is connected by either a fluid tube or fit into an "O" ring seal on the master cylinder. You need to find out what kind you have and what you'll need to replace it. If you can't find a replacement master cylinder reservoir any other place, you'll need to get one either from a dealer or a wrecking yard.
If it comes on when you step on the brake pedal you might need to bleed your brakes. Also check your brake fluid in the master cylinder.
