Hey guys, so truck started squeaking loud at me a few weeks ago on the way home one day haven’t driven the truck since decided last night to tear into it. Didn’t figure it was pads because I only have 40k miles... pulled the pads amd rotor on the passenger side and the rotor is shot, I know I’m doing front rotors and pads now... but do you guys think my caliper is stuck? Pics don’t do it justice how bad the back side is, and that pad is completely shot.
Were the pads tight and unable to slide freely on the slide rails? I've had good calipers but pads were so tight I had to knock them out which seems to cause what I see on your rotor. I grind the ends a little on new pads to make them a little sloppy on the rails....makes for more even rotor wear.
I’ll throw this out for consideration: Half the times I thought I had a stuck caliper, the problem ended up being a brake hose. Of course, once it sticks, the caliper is usually trashed as well.
Drivers side rotor is fine, driver side pads are fine for that matter. The front side of the passenger rotor is fine as well, it’s the back side that’s really bad. I need to go out and inspect the brake lines to make sure nothing is pinched. This thing has been off road maybe 1 time and it was on a dry dirt road getting back to a farm pond for fishing, I do live on gravel though and in Iowa so road salt is an issue. Everything seemed to move freely on the guides, and the front pad moved freely inside the bracket the rear one not so much but it was up against the rotor with the caliper on did come out fine though.
Just went out, had my wife pump the brakes. It’s not holding pressure at the caliper when I release the bleeder valve... would assume that’s not a pinched line then? Also, the pistons do not return at all.
Unless you have some other significant fault, like a really bad wheel bearing or a severely warped rotor, the pad retraction is so slight you would not notice it. If you want to test to see if a caliper is sticking due to a faulty hose or hydraulic system, you apply the brakes, release the pedal and try to turn the wheel. If the wheel is hard to turn, then that is probably a fault with the brake system. But the first clue would be very hot brakes and a stink from the hot pads.
Im leaning towards a stuck (or sticking) slider pin... only one of them. That or you have a crack in one of your caliper pistons... do the inside pads have a taper to the wear on one end? Either way, new passenger caliper (If you can get reman's cheap, just replace both driver and passenger) new pads and rotors are in your future.
I had a flexible brake line fail internally on my Excursion which kept pressure in the line and caused a similar issue. I now firmly believe in changing brake fluid on a regular basis.

This is exactly what I was thinking, heading After work gonna do calipers, rotors, and pads on drivers and passenger sides. Probably go as far as flushing out the lines with new fluid too. Checked the rears on my lunch, and they still look new. I’ve been getting a wobble in my steering wheel after I had fixed this issue with changing out about every component in my front end... wondering now if this has been the culprit.
