Why would front brakes on a '98 Ford Taurus start squealing a few days after installing softer pads and applying Disc Brake Quiet to the shims?

Check the rotors see if they're smooth inside and outside. If they're not smooth, or if they're so smooth that they're shiny like chrome (which brake pads can't grip as well), you can get them milled at some auto shops, but also check if they're still thicker than minimum allowed thickness (this figure will usually be marked on the rotor). If they're at or below minimum thickness, replace the rotors (replace both left and right side at the same time, so both wheels brake as identically as possible, so the car doesn't pull to one side as you brake). You may also need to replace the brake pads with higher-quality ones.
