    Wrong distribution of lining (shouldn't be so close to shoe end at end of shoe that mate with cylinder)?

    The problem is that unlike us, the manufacturers are not sufficiently smart thereby bewildering some owners and most unskilled mechanics.

    I have seen at least half a dozen Smarts with this problem. Long brake pedal travel caused by wrongly fitted brake shoes.
    The adjuster mechanisms are marked left and right (G, D, L, R depending on where made). Left and right here refers to whether mechanism has left or right hand threads, not which side they are to be fitted on the vehicle.
    Adjuster with right hand threads fits on left side shoes.

    Why is this important? You try figure it out.

    Because the rotational direction imparted varies side to side as it is mounted differently in plan view - ie symmetrically viewed in plan and would be asymmetric in the same view if similar threads were to be used on both sides. Do I get the coconut?
