I pulled my front pads off today because I'd get a bit of a shake when I was stopping from highway speeds. Calipers were great and so were rotors, the pads were garbage. Lie o meter said 10.2 and hand calculate said 10.1

Check your rear brakes. I never had a problem with the fronts, but the rear calipers were a different story. Driver side one stuck twice and required replacement both times. Passenger side was replaced once.

This happen on my 06 the day I took it off the lot (used) except that it froze so bad you'd have to accelerate hard just to break it lose from a stop. Not to mention how incredibly hot it became. 100 point pre sale inspection my a$$. The 08 had smoke and heat the day I picked that up and I called the dealer as his response was "it didn't do that when we had it". So I gotta dig into the rears to see what's up. Not to mention when at a stop and pressing firmly on the brakes I get a nasty sound (like a heavily rusted spring expanding) that I fixed once but thinking the slide pins need servicing.

Mine made that sound too. It was a groove worn around the circumference of the slide pin bore in the caliper. I had to replace the caliper to correct it. Lowest price on calipers for these trucks seems to be advance auto. Make sure you replace pads too.

EDIT: I remember the new owner of my old truck texting me a week after he purchased it and said that he had to replace the rear calipers again after it locked a rear wheel while brakeing at highway speed. That means the calipers I installed were approximately 3 years old at that point.

Was yours coming from the front? That's where my noise is? But it's not consistent.

Well i recalculated my mpgs today, i got am averaging 9.8 in town and ~13.9~14.0....it keeps going up lol. Should I be on a quest for 235/85/R16 tires? I got a worn out set of 265/75/R16s on there. They are running on the wear bars...

Sound was hard to pinpoint. I actually thought it was the center support bearing initially.
