On the driver's side the wear was super uneven. Part of the issue (I think) is that somehow the front caliper pin bolt didn't get put back on in one major service (that I did) so the caliper was rubbing on the inside of the wheel. I think the heat generated by that messed it all up and the pistons were sticking.
On the passenger side, one of the glide pins was stuck hard, the pin boot was destroyed.
And I got a complete fluid flush out of it at the same time.
