09 Mariner front brakes locked
So my front brakes aren’t releasing. My front brakes have been dragging and are almost staying locked. I replaced both front calipers, and it seemed to fix it. But a couple days later, I could tell they were still holding, as I would drive off. Today I removed the calipers, and could not press the piston back in, on either one. The only way the pistons would release, is if I opened the bleeder screw. So what’s keeping my front Calipers pressurized? 190,000 miles on it. Thanks for your help. No ABS light, or any other indication of a problem.

If any air managed to get into the ABS control module , it is next to impossible to get that air out without a capable scan tool to open the solenoid valves. What might be happening is the air gets trapped and expands and applies the brakes.There could also be a problem with the dump valves in the ABS module. Are you sure the brake pedal is coming all the way up?
