I went to replace the front disc brakes, and the caliper on the drivers , the pistons would not come out, so i went and bought a caliper, i put it on and sometimes the caliper would stick and the wheel would lock up, so i got another caliper and it done the same thing, i replaced the pads on the passenger side, and i have no problems, but on the drivers side, i can not get the pistons on the caliber to extend and when they do they lock up the wheel and i have to bleed the brake to make it let up and when i pump the brakes it does it again, I can not seem to solve it, everytime i get the pistons to push on the pads they lock the wheel up, this is my second caliper and i do not know what to do, I am afraid to drive it to a shop for fear of it locking up while driving.

If the caliper locks and won't release until you open the bleeder valve, there is a good chance the rubber brake hose going to that caliper is bad. I have seen times that they will allow fluid one way but not the other. I would give that a try and see if it helps. The hose shouldn't be too expensive. Also, are you sure the slides on the caliper are free.

Let me know if this helps.
