Working night [shift] for following day at the hangar; I was assigned to B757-200 aircraft with Mechanics Y and Z. I decided to change the # 8 [Main Landing Gear (MLG)] Brake per 32-45-01 and # 8 tire per the Aircraft Maintenance Manual AMM 32-41-10. Once the tire was off; I proceeded to remove the brake. I performed all the removal and installation of the brake. The only assistance I needed was to lift the brake onto the gear. All maintenance was complied with per the manual.
I (Mechanic Z) was involved in an Overnight Check of a B757-200 aircraft on Pad E [one] morning. I witnessed Mechanic X as he finished safety wiring the hydraulic line of the brake. As part of a team player; I assisted Mechanic X with the job by signing-off the removal and installation of the # 8 Main Landing Gear (MLG) Brake Assembly; as well as the tire; Overnight [Check] and other Work Package Job Cards. Appears that # 8 Brake Drag Link Assembly on the aircraft was damaged in ZZZZ. [Recommend] signing-off your own work and yours alone.
Two Mechanics report about their involvement with the removal and installation of #8 brake and tire assembly on the right main landing gear of a B757-200 aircraft.
