My rear pads were smoked at 36k miles, slides absolutely not sticking. The slide bores, the slides themselves, and the grease.. all immaculate. Changed the pads myself with much swearing about the stupid spin-em-in pistons.
The last time I took it in for a service.. around 38k.. the tech (for the first time ever) actually measured how much pad was on its backer on all 4 corners... ready for this?.... the fronts had 8mm, the rears had 9mm.
My truck had gone through *at least* 9mm of pad in the rear over 38k miles while only using a measly 1 or 2mm up front
A somewhat popular theory on the '5g' site is that the trucks can/will/do engage the traction control much more frequently than what's indicated by the dash light, leading to the incredible amount of wear on the rears.
I'm personally not sure how strong of a theory that is.. considering that my modulation of the trucks gas pedal was on-par with how an 80 year old man does it.. but who knows.
Definitely the first vehicle I've owned thats needed rears first.
