Caliper sticking issue.

[Effenpig]

Since this thread seems to come alive every two years I figured I'd do my part.

 

Just thought it should be pointed out that the poster first several posters are incorrect about the "little rubber tubes" that come along with the pin seals. Those little rubber tubes are the guide pin bushings and slip over the small end of the caliper guide pins. You have to dig the old ones out of the caliper bracket to replace them

I had this problem on my 05. Front hubs go out, put grease on abs sensors, front brakes would stay on, worse was locking up as you described. Swap front hubs out.

I always change the brake hoses when changing calipers. A good indicator that your hose has a restriction is that when you crack a bleed screw, no fluid drips out. I recently replaced both front calipers on my 2001 Sierra, new hoses, nice high pedal, like new. AC/Delco remans are $47/each on Amazon, and they send you $30/core when you return them, and they pay the ship. That's $17/each!

Well, you didn't mention the ABS pump and you might have selected the wrong parts and or put them on incorrectly.  The wear indicators go on the inside for example.
