Jeep Wrangler Brake question

Same problem on my '04 Ram with disc brakes all around. The problem with mine is the drivers side front caliper isn't retracting but it's not the caliper pistons. It's the sleeves where the caliper mounting bolts go are sticking/seizing. The caliper and pads are staying against the rotor but the piston is retracting. The pedal goes to the floor once then it's fine until the next stop. I love doing brake jobs in the winter.

Just something else you might want to look into.
