Question about 2001 Toyota 4Runner
Ensure your parking Brake is full disengaged if its full disengaged
You have a problem with the ABS system. Could be many possibilities such as wheel speed sensors or their wiring, or a problem with the ABS motorpack or Brake controller module. This is not a Zen problem of equillibrium in the brake pads. This is a functional or electrical problem in the ABS which also is the Traction Control. You need to get to a repair facility to fix this. It will probably cost you but it will be cheaper than guessing.
