Narrative:

I was told by my supervisor to help my partner do a brake deferral because the crew had found both brake wear indicators missing in his preflight. There was a joint effort between my partner; my supervisor; and myself to complete the deferral and the maintenance procedures. My partner was pulled off mid-way through to service hydraulics; being directed by the supervisor. The crew was on the aircraft; so they were involved in the [procedure] as well. Once the [procedure] was complied with the plane was dispatched where it taxied a short distance and then stopped. The crew reported the brake felt like it was dragging and also had a higher temp than the others. We were directed by the manager and supervisor to reverse the [procedure]; hooking up the hydraulic lines in an effort to get the wheel to free up and allow the ground side to push the plane back into its parking spot. After parking the plane we documented our work performed and left.
