I have done a total brake overhaul on my 2004 Runner SR5. The normal front caliper seize etc. So What I have done, New rotors front and rear, new pads front and rear, New calipers front. Well as we were taking over the passenger side rear rotor it was a *****! The brake shoes did not want to let her go and come off. Finally got it off but one of the pins with a spring assembly was flopping lose that held the brake shoe where it's suppose to stay. My question, is do I need to pull the hub to get to the spring assembly to make it functional again, or is there a trick to working on the back drum area of this horrid design? I have searched all over and can't find a diagram for anything on the drum area/adjustment etc. Thanks anyone...
