Narrative:

We were assigned to fly aircraft X for our duty day. The aircraft was one we had not yet flown this tour. A previous crew had written the airplane up for a brake fluid leak on the right main landing gear. Upon preflight inspection I noted that the brake assembly was dry of fluid and in reviewing the log book I noted that a mechanic had signed the write up off as being repaired. After starting the APU and setting the brake in preparation for departure we noticed that there was a puddle of brake fluid below the right main landing gear brake assembly and the brake assembly was wet with brake fluid when we did our pre-departure walk around. I am seeing more and more write ups that are signed off as being fixed only to have the same failure occur again either immediately or within a very few cycles. Better quality control and or/better maintenance vendors need to be employed.
