Had my front brakes replaced last fall~mechanic replaced both rotors, pads and one side on the ABS sensor that had been damaged. Brakes worked great. Calipers seemed fine.
A couple weeks ago started noticing noise in the rear brakes and knew it was time to replace those.
My mechanic replaced both rotors on the rear and one set of calipers along with brake fluid line. We bled the brakes, but the new caliper locked up. We bled them again and got the caliper working, then the other caliper locked up. We wound up replacing both rear calipers with new ones as well as new brake fluid lines.
We'd bleed the brakes, but it didn't seem like we were getting much for brake fluid to the rear. Pedal seemed a little softer than before, but the rear calipers were working.
No ABS or brakes lights have ever come on.
Haven't driven the truck much, but yesterday we went to town...and after a brief stop, the brake calipers locked again. I had to get the truck home, so we could only drive it about 20mph. (fortunately didn't have to go far)
Do we need to try replacing the front calipers too?
Thanks for any and all ideas: hoping its just something we overlooked.

You need to find out why calipers are locking up.
When they are locked open bleeder screw and see if that releases them.
Post back what that does.
On bleeding abs brakes a ABS capable scanner is needed to bleed the right.
