My experience with the Front Disc / Read Drum installations is that the front pads need to be replaced three times for every replacement of the rear shoes so I'm perplexed about this.


Not sure how true but one brake site said in this typical application the rears were mostly along for the ride. 60-70 percent of the brake action was on the front with the rears mostly there to provide a bit of drag. Supposedly the rear drums come in a moment before the fronts to get things started so the car stops and stays in a straight line but the fronts do the majority of the work.

Went on to say as the weight and inertia shifted toward the front in the typical nose down configuration, rears had less weight and less contact with the ground and had less stopping power. If that's the case I would think that also means less wear on the shoes.

Believe Packard alluded to that weight transfer action with torsion level. Think the explanation went something like as the car's weight shifted, the action would twist the bar increasing it's force and transfer that extra energy to the rear axle. In addition to keeping the car level it also increased the rear tire contact with the road providing for safer stops.
