[QUOTE=ShuttlePilot;321459]I think this bit of info is a big deal right here. Since this has happened on both, new and old axles and symmetrical on both sides I would direct my investigation away from anything brakes hanging on the axle. Specifically I would do an engineers assumption that everything beyond the hydraulic tee on the rear axle as "good". I'm still in the camp that thinks this is hydraulic not mechanical. /QUOTE]
Well, I know for a fact that this is a common problem on these vans, I know more than one person who has had this issue, so it might not be such a surprise that it has happened on two different axles. One of my buddy's actually swaps the pads from side to side to even the wear. It also happened on my last SMB, but not to the degree I'm seeing now. As for the hydraulics, everything from the hard line connection point back to the rear axle is new including new SS flex lines. So far, the fronts have been wearing evenly, and since they share the same master cylinder and brake booster I'd guess they are ok. It could be that the ABS unit is holding pressure on the rear calipers, but if that was happening, it still shouldn't account for uneven wear, just accelerated wear. I'm still thinking that one sticking piston in the caliper could cause the caliper bracket to twist and prevent any sliding. When I removed the slider pins from the old caliper, they came out easily, were well greased, and moved freely once the caliper was unbolted. I'm hoping this latest set of "remanufactured" calipers are a better quality, but I won't really know for several months.
