Our outback runs the rear pads out first too. I think maybe its TC or stability control just being a bit over active?Do some vehicles have rear brake bias?
My Jeep Patriot rear drum shoes wear out before the front disc pads, about 25K miles difference. Is it due to rear bias? Or, the rear Akebono shoes are only EE friction rating, so maybe they are "soft" and wear faster? There seems to be almost no rear drum wear.
Soft shoe material or rear bias are my reasons and/or question.
