So if it was the brakes that were faulty, then the last engineer to look at them better have a good answer lined up...
Yeah, like each brake gets a full overhaul every transit. After initial assembly, then fitment, the routine attention they would receive would be a general visual inspection by pilot and gnd staff on walkaround (depending on the airline operational procedures).
There is only so much you can assess from looking at the ass end of a brake.
