I have a 92 Grand that has been having a brake problem. Last year the left front brake started sticking. The caliper would not relese, and would burn up the pads. Well I replaced the calaper, and it seemed to fix the problem. Well then it came back. I figured the calaper I got was bad, so got another replacement. No go. Still sticking. All the slides are good, and the calaper piston moves without the line attached, but will not retract when hooked up. Any thoughts? The van has a 3.3L and has the ABS system. Anything in there that could be restricting the fluid on that one brake?? Thanks for any help.
