Narrative:
Aircraft was written up for a right main strut leak. I took the call with a co-worker who acted the inspector for the task. We performed the maintenance required following the maintenance manual.I have since learned that a brake line failure or fitting failed causing a brake to lock-up a few flights later and may be related to the maintenance I performed that night. While I don't recall the specifics of the task I do recall the operational and leak checks related to the strut and brake installation.as of right now I'm unsure of how this could have happened. I do my best to check and double-check my work. Since the failure occurred in the scope of my work I can't help but feel responsible.
