Drilling through brick

Hi everyone, I'm a newcomer here and would like some suggestions on a project I'm doing. I've attached a photo for reference, and basically I've decided to take four legs to a carport like you see pictured, and I want to mount them to square red bricks like you see pictured for weight.

A good way to secure them to the bricks that comes to mind is to drill some holes and secure them to the bricks with masonry screws. I have a hammer drill for this, but I've never done this before so any suggestions on this?

I have heard that tapcon screws wear out over time outdoors, and this is an outdoor project so are there stainless steel masonry screws I can use instead that will better withstand the elements?

If you have another idea of how I can secure the legs to the bricks I'm open to that as well.

 

I don't think the fastener will be your problem as the brick you picture may, over time, crack no matter how you secure it. Tapcons will work just fine. My only concern is the thickness of the brick. Too thin a material, and your fasteners become a moot point. I would probably opt for drilling clear 1/4" holes through the brick and fasten the flange using stainless bolts and fender washers or matching plate with properly drilled holes on the bottom with a nut on that. I am assuming these will be set out in a yard, right? The nut will protrude slightly below the brick, that is why I ask.

 

Thank you for responding Chandler. Also thanks for pointing out the thickness of the brick, I should have mentioned that, but they are 2 inches thick.

The nice thing about these bricks is I have several of them around the property, and they have held up well, and if one should crack it would be a matter of just replacing it. I was concerned about those tapcon screws though, but I'll take your word about them holding up.

These will be set up out in the yard, right on top of dirt, so there is some flexibility underneath them, they won't be on concrete or anything. I'm just a bit confused about how to attempt this, being I've never done this before I want to be sure I drill the right size hole, etc., as to not waste a brick. I could even get away with just securing two holes on the legs, I wouldn't necessarily have to secure all four open holes.
