I need to replace the rear brake pads on a 2004 Highlander V6. I've replaced pads on other, older cars many times in the past; however, reading posts leads me to believe that this may be a little different. Does the brake line need to be removed from the caliper? Is a special tool, star socket or wrench, required to remove the caliper? I'm not worried about turning the rotors, just replacing the pads. I'd certainly appreciate any advice. Thanks.
