1994 Ranger Brakes
 

Just bought a 94 4.0. Brake pedal is mush and when I come to a stop it feels like the brake pedal kicks back at me. RABS light and parking brake light stays on, no leaks from the master cylinder, any lines, or calipers/wheel cylinders. Rear drums are pretty rusted so thought I would just go ahead and re do them.
any thoughts?
