hey there, i need to do some maintenance on the rear brake drum, specifically the pass side squeaks in rotation with the wheel, but only occasional. it seems to leak some fluid too, so i thought i would take it apart and see what it needs. anyone have any tips on this? i took the wheel off, but cant seem to get the drum cover off, do i need to remove the whole assembly from the rear, to just get the cover off and replace the brake shoes? the service manual is not much help, it says to remove the whole assembly in the axle removal section...
