Default Brake Caliper Sticking

Ok, I tried to search the forum and got 0 matches, so here it is... back from my long trip and noticed a high pitched squeaking coming from the Driver Side Front Wheel. also noticed that when I did not have the throttle engaged the truck would stop faster than the normal engine braking allows. I assume I have a stuck caliper which really irks me b/c I just replaced both of the fronts during the last brake change due to leaking seals . I bought them from Auto Zone and have a lifetime warranty on them. Is this something normal on our trucks? any advise would be appreciated. I have not looked into the brake pads and rotors ( also brand new) to see their condition but I assuming they are probably shot.
Thanks,

One or both are sticking. I'd take the whole shebang back. You'll have to do both sides again anyway. Calipers, rotors and pads.

Molly lube in a high temp application on the slides and that should do. You might try that at first to see if its just not properly lubricated. the other thing that happens is the seal on the new caliper may be bad and not returning properly or its just in the right spot and is not pulling back the piston.

Mike you'll have to take a look to see what happened. Maybe you can free up the caliper and get away with new pads on both sides. But if the rotor is toast on the one side You'll have to do both. I'll keep my fingers crossed for ya.

Why replace both sides if only one side is bad? It does sounds like they both are sticking if you are not getting any pulling from one side or the other.

Like everyone else said, lots and lots of lube. Every time my tires come off for a rotation I check each caliper to make sure the pads are wearing evenly. If they aren't I know its time to pull them apart and clean up the slide pins.

Because its not safe to do so. Brakes are a rather important item that one should not take risks with.

True, id rather get the same amount of life out of both of the pads but rotors wear just like brake pads too so hopefully the rotor thickness isnt too different. Id take it back and ask them if their warranty for their brake caliper covers the cost of it heat scorching your rotor and ruining it.
