Well I just did the brakes on all four corners of my "15",
she has a bit over 76,000 miles on her.
The brakes hadn't worn evenly the drivers side front was completly gone on the inside pad,
not even a 1/16th of an inch of pad.
Replaced pads and rotors the fronts were easy to do,
the rears were a royal pain in the butt.
Had to put the pads in the mount before it was installed on the truck,
and it is ridiculous to have two different size bolt heads holding the calipers and the caliper mounts.
The front calipers took a 13mm, the rear calipers a 10mm.
The caliper mounting hats on the front took a 21mm or 13/16th socket the rears a 20mm.
Didn't go real fancy with the pads and rotors got them from RockAuto;
used Power Stop Z16 Evolution Clean Ride Ceramic pads and Power Stop Evolution Geomet® Coated Rotors.
The brakes do feel much better then they did,
can't say they are better then stock or not it's been to long to recall how they were when new.
