Human Factors; Incorrect / Not Installed / Unavailable Part
Aircraft was reported to have a crack in the Captain's side storage container. Inspection of this container showed several repairs had been attempted on this container. I reapplied the previous repairs and secured the crack by drilling a hole through the container box and secured the crack with a tie wrap; then filling with a bead of silicone. Evidently without my knowledge; a wire was damaged during the process of drilling through the fiberglass. This damage caused an auto brake malfunction on the subsequent log page. During troubleshooting of the auto-brake MEL; Maintenance found the damaged wire. I was concerned with getting the aircraft out on time with no delay. This component had been damaged many times before and would have taken a long time to repair or replaced if the item was in stock. Remove aircraft from service regardless of consequences to flight schedule.
While attempting an interim repair to a fiberglass panel located in the flight deck; the Maintenance Technician inadvertently drilled into a wire bundle; causing an auto brake system malfunction.
