You I have jeep wrangler 2000 that caliper wont return. Break stuck.

Hello,, if the brake caliper piston and slides move freely when not installed, but when installed do not move - then it's likely a concern with the brake hydraulic control unit. I'd seek guidance from someone with a chassis based diagnostic tool that can inspect these functional components. If the anti-lock brake system has a malfunction, it can continue to pressurize the system when not needed.
