Brake pad wearing out

If that is only the pads on one side that are wearing out that quickly, the caliper is stuck on. You can prove that by stopping on a slight incline, shifting to neutral, then releasing the brakes. The vehicle should creep downhill on its own. If it does not, place a block about a foot downhill of one tire so you do not look funny chasing after the car, then open the hydraulic system at various places to determine where the brake fluid is being trapped. You might start by loosening the steel lines right at the master cylinder. If that works we will need to have a long discussion as the system was likely contaminated with a petroleum product.

Open the bleeder screw on the locked caliper. If that works, suspect the rubber flex hose.

If the brakes are not sticking, you may have a tripped valve in the master cylinder. I do not know if that is used on your vehicle, but this causes a lot of trouble on GM front-wheel-drive cars. Drive at about ten mph, then make the wheels lock up and skid on sand or dirt. Check if both front tires skidded or if just one did. If only one front brake is working, you may not notice any symptoms other than rapid pad wear, but that typically takes a few months to show up, not a few days.

My suggestions do not have anything to do with the caliper. Most people mistakenly replace that first, but calipers do not really cause that much trouble.

The brake hose may be at fault, they can deteriorate internally and small flaps of rubber brake down and block the hose, these can act as a one way valve causing pressure retention.
