Narrative:

I followed tasks for installation of the main landing gear lower anti-rotation sleeve in accordance with crj 900 aircraft maintenance manual (amm) 32-11-400-802 pertaining to the aircraft serial number; this task called for the task to install breaks; which were followed in accordance with (in accordance with) crj 900 amm 32-43-26-400-80. This task then called for the bleeding of the brake system in accordance with crj 900 amm 32-43-00-870-801; the task proceeded to lead to an ops and leak check of the brake unit iwa crj 900 amm 32-43-00-710-801 during this task no leaks were found at the time; therefore ops and leak check was good at the time.with the lack of experience I have with this system I am unsure of the exact cause of the issue; I cannot see what I could have done differently. I followed my task to an exact measurement as I am told to always do as such.
