On the walk around in ZZZ; I noticed the right outboard wheel brake assembly appeared misaligned with the other wheel. Work was done on that brake in ZZZ1 before we flew the plane to ZZZ. The First Officer had done the walk around in ZZZ1 and verified the brake wear indicator pins were good; but did not notice the misalignment.I believe the cause was improper installation of the brake assembly.
The brake assembly was installed wrong. It appears as it is shown in the picture. The right brake assembly was rotated up. During the walkaround I checked the brake which was good. Unfortunately; I did not notice that the brake was rotated up.The brake assembly was not installed correctly by the maintenance guys.
B737 Captain reported that a brake assembly was improperly installed.
